Well, it's not going to be that easy, apparently... I booted up RH7 and am trying to get that happy so I know what to set up Midori with. XFree 4.0.2 with the "cyrix" module doesn't even want to see the graphics controller on the MediaGX at all, even though it's there plain as day in the lspci output, and the XFree guys say it's a preliminary move of the 3.3.6 driver to 4.0, and to test it.
Well, it doesn't look like it works.
Given that, it appears that XFree 3.3.6 sees the controller, and 3072K of video ram, but I can't seem to get the refresh etc figured out - anyone have an XFree 3 config that works? Then I'd have to make an MLZ out of it all. Non-trivial.
Another option, apparently, is LibGGI, but the website for that seems to be dead and gone. Apparently, though, GGI has support for the MediaGX and there's an X server that will run over it.
Anyone have any ideas?
