I deleted OSX and did a Linux only installation. Why waste the meagre 30G space when I wont need OSX. Follow the instructions in the Gentoo handbook. I did a stage 2 installation and downloaded the latest Linux kernel 2.6.16 and compiled it myself. Sleep works finally !!!
My /etc/make.conf file

The iBook has only one mouse button !!! You can assign some other keys for the middle and right buttons. This will work if you have enabled the option in the kernel. Then add the following lines to /etc/sysctl.conf
/etc/sysctl.conf
dev/mac_hid/mouse_button3_keycode = 126 dev/mac_hid/mouse_button2_keycode = 125 dev/mac_hid/mouse_button_emulation= 1
This assigns the middle button to the Apple key (which is on both sides of the space bar key) and the right button is Fn+Apple.
pbbuttons is great. Volume, brightness and CD eject keys work well. With gtkpbbuttons you can get a nice display while these keys are pressed.
Use the ide-cd module. No need for scsi emulation for cd-writer. To check your cdwriter do
$ cdrecord -scanbus dev=ATA:

and while writing specify the device as, for example, <tt>dev=ATA:1,0,0</tt> or you can also add the following lines to <tt>/etc/default/cdrecord</tt> file
CDR_DEVICE=matshita matshita= ATA:1,0,0 -1 -1 ""
To allow all users to use cdrecord, remove the SUID bit from cdrecord
chmod -s /usr/bin/cdrecord
You may have to specify the device as <tt>/dev/hdc</tt> instead of <tt>ATA:1,0,0</tt> for this to work properly.
Use the therm_adt746x module in the kernel. This module also allows you to read the cpu/gpu temperature and fan speed from /sys/devices/temperatures
Load the following modules for sound to work properly
i2c-keywest i2c-dev soundcore dmasound_core dmasound_pmac
These modules are for OSS; I had problems with ALSA, but it might work with the recent kernels. Try ALSA first and use OSS if it doesnt work.

Suspend to RAM works very well. Enable the required options in the Macintosh drivers section in the kernel (see my config file) and install <tt>powerprefs</tt>. Some usb modules can cause iBook to hang upon suspend. These modules must be unloaded before suspending. Put the <tt>modules</tt> file given below in <tt>/etc/power/event.d</tt>
I use powernowd to reduce the cpu clock when the cpu is idle.
You can read the cpu/gpu temperature and fan speed from <tt>/sys/devices/temperatures</tt>. I use torsmo to display these informations on the screen. Torsmo was available in gentoo portage but seems to have been removed now. Anyway it did not work directly and I had to do a small hacking. You can download the file from <a href=”torsmo-0.18.tgz”>here</a> and compile it yourself. Copy the executable to <tt>/usr/local/bin</tt> and put the following line into your .fvwm2rc file
+ I Exec /usr/local/bin/torsmo -d -a top_right -w 0x48 2>/dev/null
This will display the output at the top right corner of your screen.
You can install qemu, compile the binfmt_misc module in the kernel and run the script <tt>qemu-binfmt-conf.sh</tt>. This will allow you to run simple binary files from other architectures like x86. However if run time libraries are required then you will have to supply them. You can execute this script automatically during boot by giving its complete location in /etc/conf.d/local.start.
You can get some system information by running the bash script <tt>ibook.sh</tt>
$ ./ibook.sh CPU Clock Speed: 1199MHz CPU Temperature: 43 GPU Temperature: 46 Fan Speed : 0 (0 rpm) Power source : AC Battery charge : 4480, 96% Current : 0 Voltage : 12359 mV Time remaining : 0
Add the following modules to your /etc/modules.autoload/kernel-2.6 file
