Are you sure that you are not running XFree when this yellow distortion
occurs? It looks to me like that you are using XFree with DRI in 32bpp,
while your console uses 8bpp. Do not do that! DRI permanently smashes
accelerator state with its own setting, and this makes any other
accelerated work on the system unusable. So either disable matroxfb's
acceleration, or explain to your mga_dri that "screen invisble" should
mean "you do not own hardware, dude!".
