You should contact the linux input layer / USB HID author. It seems the
touchpad isn't properly recognized, he may be able to fix that. I don't
know anything about these new touchpads and didn't have a chance to play
with those new machines yet.

It's probably not that different from the existing chips though...

Wht do you mean ? The half bogomips ? well, it might just be a matter of
enabling support for your machine in arch/ppc/platforms/pmac_cpufreq.c
around those lines:
if (machine_is_compatible("PowerBook6,5") ||
machine_is_compatible("PowerBook6,4") ||
machine_is_compatible("PowerBook5,5") ||
machine_is_compatible("PowerBook5,4")) {
pmac_cpufreq_init_7447A(cpunode);
Though that code will probably think you are running at high speed which
isn't the case apparently... We probably need to add some code to read
back the current speed mode from the processor to get the initial speed
correct or all the kernel delay loops will be broken.
