Here's an improved GTF implementation.  I was a bit delayed because I
was trying to find a way to do square roots without using floating
point.  The diff is against linux-2.5.54 + your latest fbdev.diff.

Applied.

but is more or less usable.  Tested with i810fb and rivafb. (For rivafb,
I have to use a hacked version. The latest one does not work for the
riva128).

What hack did you do? That is based on the latest riva driver from 2.4.2X.
 

I just combined the old riva_hw.c in linux-2.5.52 with the new fbdev.c
code.  Not too sure why, either the newest riva_hw.c has dropped support
for old hardware, or we are using it incorrectly.  If I'm to guess, the
new riva_hw.c did not come from linux-2.4.20, but probably from Xfree86?

BTW, I downloaded the source code of read-edid, and it seems that the
following monitor limits are parsable from the EDID block: HorizSync,
VertRefresh, DotClock, and GTF capability. We may change info->monspecs
to match that. Also, the EDID contains a list of supported modes, but
there's only 4 of them(?).  

I figured monspec would have to be improved. I'm looking into the EDID 
info right now. I'm also looking at read-edid. Next I need to figure out 
how to use i2c to get this info.

Good luck :-)
