yeah, i tryied the "unsupported" option, didn't work, and after some more online research i found out that the chipset isn't supported, but that somebody had a kernel patch for teh 2.4.20 kernel (which im using) and it worked, i haven't found any downloads of it, but if i do i'll post em here.
nevermind what i wrote above, i tried to load the agpgart module with the unsupported option with X started, and it didn't work, but without X started it DOES work. check this out:
AGP Rate: 4x
Fast Writes: Disabled
now to do some research on fast writes and SBA to find out what they are
