No, I have to use this machine, so most debugging is off. FYI, I've
tried the driver a number of times since I've had the machine (~1 yr),
and the results have been either spectacular lockups, or unable to
attach to the hardware.

Kernel conf is mainly GENERIC:

include         GENERIC
ident           ZOOT
machine         i386
nocpu           I486_CPU
nocpu           I586_CPU

options         SC_PIXEL_MODE
options         SC_HISTORY_SIZE=1000
options         VESA
options         SMP

device          crypto
options         GEOM_ELI

nooptions       INVARIANTS
nooptions       INVARIANT_SUPPORT
nooptions       WITNESS
nooptions       WITNESS_SKIPSCAN
options         ALT_BREAK_TO_DEBUGGER

device          atapicam

device          vt
device          drm
device          i915drm

options         NDISAPI
device          ndis

The device ids of the card are:
none0@pci0:8:0:0:       class=0x028000 card=0x135c103c chip=0x42228086
rev=0x02 hdr=0x00

This is of minimal importance to me - I have wires everywhere and a ural
usb stick for when I haven't - but if it helps get the driver debugged,
I can try any patchs.

Cheers

Tom
