I'm still working through my Radeon problems.

I think my next step is to try upgrading the radeonfb driver, to see
if there was more refinement there that will help.  As always, I
appreciate any and all help.

This indeed was the cure to my problem.  In short my symptom was
that I could use fbset to latch a new mode (resolution), but any
call to fbset would also cause the card to drop the sync signals.
I found I could restore the video, tho', by rocking to another VC
and then back.

I was using radeonfb verson 0.1.4 (as shipped with RH 7.3).  I found
and applied a set of patches to four files: radeonfb.c, radeonfb.h,
radeon.h and pci_ids.h (actually the pci_ids.h was more of a merge
than straight patch) to bring the driver up to v 0.1.6, and it
immediately started working much better.

I'll tack on some benchmarks results -- this from a Radeon card
plugged into a PCI slot on a 400 MHz Celeron x86 board running
(mostly) RedHat 7.3.  Makes it clear which tested functions are
accelerated, no?

There is also a version 0.1.8 available and even a .9 I think, so I
may wind up making further upgrades in the future.
