Radeon support (was Re: (no subject))

[Adam K Kirchhoff <adamk@voicenet.com>]

Me again,

	So I think I might have a better idea of what's going on... I did
some testing with the Radeon framebuffer tonight, and can only seem to get
it to work with just two modes: 1024x768@70 and 640x480@60.  I've tried a
number of others, which worked with the DVI output of my 7500, but don't
seem to work with the VGA port of the card.

	Any ideas?
