Oh, ok, I thought so. Some questions:
Do I really need acpi_video?
Can I use both AGP and acpi_video at the same time?
Do I need to load i915 kernel module?

Yes.

Ok, I understand, I'll try your patch and let you know whether it solves 
the problem or not.

It is strange though I see mouse pointer in center of the screen, but it 
doesn't move.
As I recall it was working without moused when I first installed 
FreeBSD-6.1-RELEASE.
I'm not quite sure, I did several updates to RELENG_6 and somewhere July 
it didn't work without moused loaded beforehand.
Maybe it is ACPI related problem, but it is only my opinion.
