ATI Technologies Inc Rage Mobility M3 AGP 2x (rev 02)

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

Oh. A Rage 128 chip with a LCD display. Then you are out of luck right 
now.

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.

We it sort of is old but yet new. I did port alot of the code from 2.4.X. 
to the latest tree. I haven't ported "thee" latest patches tho.

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.

It there but only for PPC platforms. Hopefully with the new fbmon.c code I 
will be able to have this work on ix86 very soon.
