Does the frame buffer driver you wrote for x86 Linux relies on the card being
initialised by the video BIOS on the card? If not, it'll work out-of-the-box.
If yes, you'll have to make sure a similar initialization is done on the MIPS

Fbmem and fbcon should work fine. They are not architecture specific.

And if these work, XF{68,86}_FBDev should work as well.
