Great News!  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)
