This is a r128 based chip, which lacks some of the proper support for
LCD stuff (especially automatic retreival of the EDID from BIOS) that
we have in radeonfb. If you feed the driver with a suitable mode, it
should work

I haven't yet checked which codebase is in there for rivafb, I have
started collecting various patches around & doing my own fixes, I have
a version here that works on PPC with GeForce2 & 4, though I still
have problems with accel on the GeForce4. It's a 2.4 code base right
now, I haven't had time to clean that up and release a patch though.
If 2.5 still has the old codebase, then GeForce4 isn't properly
supported yet.
Note that if you have a flat panel, then the problem of properly
retreiving the EDID to get a suitable default mode is also present
there, unless James added some support for it.

Ok, I've seen that James added various fixes to 2.5 radeonfb, I still
have to port some of my 2.4 ones to 2.5, I except those chips to be
properly supported with fbdev.
