Hi Peter,

> pci1: <network> at device 18.0 (no driver attached)

  This is the first problem: the GEM driver needs to be updated
with new PCI IDs. That's an easy fix, and I'll get that done pronto.

> panic: nexus_alloc_resource: no pic attached

  This has also been seen on the 17" P'Book. The algorithm used
to locate the interrupt controller in the OpenFirmware device tree
isn't working on these models.

  At the OpenFirmware prompt, would you be able to do

0 > dev /chosen
0 > .properties    (don't forget the '.' !)

  ... and there should be a node called "interrupt-controller". If
not, the probe won't work, and that's where the panic is coming
from.

  That's because USB hasn't been probed yet so the syscons/USB kbd
won't work. With syscons disabled, the console is the polled-mode
OpenFirmware console, so both the USB and internal kbd's will work.

later,

Peter.
