R200 Microcode detection not correct?

[jason]

   I have had problems with getting dri working in the past, and still 
do, so I started going through code for my video card and related 
stuff.  I found that tracking current caused the line about loading the 
r200 microcode for my radeon driver to go and come in my dmesg.  Right 
now I have 5.3beta3, I plan to stay with 5.3 release for a while, and 
the line is missing.  I don't beleive I have ever been able to run with 
dri loaded on my nforce 2 board and a radeon 8500.  But now I can use 
agp instead of pci mode and run xorg.  If I load dri with agp my system 
now gets to the wm stage and my monitor's osd tells me it has switched 
to [EMAIL PROTECTED]  I get a black screen with some colors at the top and 
the mouse stays functionail but my keyboard seems to die.  I check very 
thoroughly and there was no Xorg.0.log made for the run when dri was 
loaded.  I only checked for the long once and crashed it by loading dri 
twice.  I'll try to get a log if it is needed.  The power button is set 
to shutdown with acpi on, it works half the time.  Maybe this was 
responcable for me not finding a long of the crash?
   My question is could this be related to the wrong microcode being 
loaded?  I know I have a r200, its even in the Xorg.0.log and pciconf 
that I have a r200.  Is there anyone that has experince on this that 
could give me a hint?  Should I make a pr for this?
