I spent a little time playing this evening, and had some luck. I build a
2.6.12-rc4 kernel, and sound and sleep both work. The CPU also runs at full
speed.

I found a patch that supposedly made the fn key work, but it didn't help me
any. I didn't try to hard. There is also a kernel patch + userspace app that
supposedly makes the trackpad work, but like Jonathan, I have a usb/kbd &
mouse, so I didn't try that either.
