Heh, I use the fbdev X driver (which uses the kernel vesafb driver). I am
already in X, and quite nicely (1280x1024x16), but right now, my vid card is
not supported natively by X (its a Matrox Parhelia, and Matrox hasnt released
their native driver for it yet). This means I'm relegated to using either the
vesa, or the framebuffer driver. The vesa driver screws up the console when
I return to it from X, so I went with the framebuffer device. It works well,
however xvinfo tells me I dont have a vid card.

I'm also wondering if its possible that this kind of option could be added to
mythtv (hell, yank it directly from xawtv if necessary!), it would be a
worthwhile endeavour, as there are quite a few people out there who use the
fbdev driver for X.

I'm running XFree86 4.2.0 :)
Aparently the framebuffer support tho, does not support the XVideo extension
(I'm not sure if the 'vesa' driver does tho, that might be enough to make me
say 'damn the console, I'll use the vesa driver' if it supports XV
extensions, does anyone know if it does?).
