I got my 1280x800 working, I had to hack up the linux 855resolution 0.3 utility, and I used the i855vidctl code as a guide, but in the end, I have 1280x800 . When I get a chance I'll clean it up and maybe submit a port or something, and if I don't, someone bother me until I do. ( I am a lazy bastard) -Andrew
