A patch has been submitted which is reported to fix the issue:

Please test it as requested.

Thank you for the info :-)

Unfortunately, applying the patch on top of 2.6.31 doesn't improve the 
situation for me, rather the opposite. Under X I get no reaction on any 
  keypress on the keyboard or movement on the trackpad. Even plugging in 
an USB mouse and keyboard didn't help, the usb port doesn't provide an 
power to the mouse (at least the led in the mouse doesn't light up).
Before X starts up the keyboard does respond, also the trackpad seems to 
be detected. Doing a suspend/resume cycle doesn't change the situation.

I'm not sure if there was a miscompilation, I didn't do a "make clean", 
I just applied the patch and did a "make". Should this be enough? 
Compiling the whole kernel unfortunately takes quite a while on my iBook :-(
I will see if I can connect to the iBook via net and get some 
information on what is happening, or maybe I try to start it up without 
X. Would it help you if I send you the logs, etc? Which information 
would help you?

Thanks,

Martin

That looks like a different problem than the one I fixed. Is there an
email thread or a bugzilla entry that describes the setup precisely, the
symptoms, kernel logs etc... ?

Start with sending the dmesg, the output of cat /proc/cpuinfo, and the
Xorg log (/var/log/Xorg.0.log)

Cheers,

Also throw in your .config (and while at it, try using the standard
pmac32_defconfig).

Cheers,
Ben.

The USB not working was indeed a separate issue, I striped down my 
kernel config before building 2.6.31 and striped it down too much. After 
fixing the config the usb is again working.

What I don't really understand is that now after I fixed the usb kernel 
config and recompiled also the adb keyboard and trackpad are working again.
To test the original issue, I did several suspend/resume cycles and my 
trackpad is still working :-).
Without the patch the trackpad was almost never working after a 
suspend/resume cycle, so the adb trackpad issue seems to be fixed with 
your patch.
Thank you very much :-)

Bye,

Martin
