[CentOS] Radeon 7000 woes, redux

The Radeon 7000 and the X.org radeon driver have had some well 
publicized difficulties since CentOS 4.2 (aka RHEL4U2). In short, the 
7000 would hang miserably, often completely killing the console. See, 
e.g.,

On Nov 29, 2005, Red Hat's Mike Harris announced the testing release 
of xorg-x11-6.8.2-1.EL.13.21, which ended up solving the problems with 
my video subsystem. That ticket was later marked closed with an errata 
release of the xorg-x11 packages:

   http://rhn.redhat.com/errata/RHBA-2006-0072.html

I installed that upgrade (xorg-x11-6.8.2-1.EL.13.25) when it was made 
available via yum, but never not around to rebooting until the recent 
4.3 release.

My (PCI, not AGP) Radeon 7000 went on strike again! The console 
crashes aren't as fatal this time around -- the screen is a mess, but 
the keyboard and mouse still respond to input (though I can't see what 
I'm typing) -- but they still render the console unusable.

For now, I've reinstalled the radeon_drv.so from Mike Harris' 
xorg-x11-6.8.2-1.EL.13.21 interim release -- which, thankfully, I've 
kept around, because they are no longer available in Mike's chunk of 
people.redhat.com -- and that's solved the problem.

I'll try to send a real bug report once I can isolate what may have 
changed between .21 and .25, but for now I thought I'd just send a 
general problem description.
