You could also try to remove the le2me_32 from the VID_RD32 /VID_WR32 macros.
I just read that nvidia cards can byteswap the config registers.
[nvidia_vid] arch 30 register base 0x30130000
[nvidia_vid] detected memory size 0 MB
[nvidia_vid] unable to setup MTRR: Function not implemented
[nvidia_vid] video mode: 16x770 at 32

Hm, video mode gets calculated from values from the 8-bit VGA regs. Maybe we 
can't use these on ppc. Depth looks sane, though.
