Sorry for a long delay - it has been a really busy week here. It does
indeed works with 256.44 just the way you describe. Though I had a
couple of strange lockups of ACPI subsystem, but I haven't had enough
time to debug them. I guess other drivers could also work if only this
wasn't a MacBook. FreeBSD can call BIOS reset, but it looks like this
doesn't work with MacBook as it has no BIOS, and would require to copy
video card BIOS into memory and execute it in emulation mode. I've
seen such a code for linux loader (to boot linux in non-emulation
mode), but I don't think it worth doing this on resume.
