Erm. Sorry about that - I just realised that there's actually a fairly 
significant problem with it :) Right now you'll perform the register 
call unconditionally on module load. You need to make sure that there's 
actually Poulsbo hardware in the system, either by registering as a 
proper PCI driver and calling acpi_video_register in your probe function 
(and unregister in your remove function) or walking the PCI device list 
looking for a psb device.
