The attached file is a draft stub driver for poulsbo. Like you said, it
will only call acpi_video_register and acpi_video_unregister when
initial and exit.
And I added the Poulsbo pci id in the module alias.

It's works to me, where can we put the driver? in driver/staging ? or
put in driver/gpu/stub ?


Thank's a lot!
