Something in the last week or two broke the r200 driver. After I cvs
update'ed and recompiled yesterday, I get this error:

(EE) RADEON(0): RADEONCPGetBuffer: CP GetBuffer -1020
(EE) RADEON(0): GetBuffer timed out, resetting engine...
(EE) RADEON(0): RADEONCPGetBuffer: CP reset -1020
(EE) RADEON(0): RADEONCPGetBuffer: CP start -1020

and it gets stuck there repeating the error over and over (the first
time it happened the log grew to almost 800mb before I noticed that
something was wrong).

Reverting to XFree86 Version 4.3.0 (Fedora Core 1: 4.3.0-42), everything
works as normal, and if I then reinstall cvs version it works until the
next cold boot. I'm guessing something isn't being initialized correctly
in current cvs.

Card is 9000/128mb under linux 2.6.0-test9 (athlon64 running in pure
32bit mode) with an lcd connected to dvi.

The (cut down) log is here:
http://www.lstud.ii.uib.no/~s864/XFree86.0.log

From the log, the card gets detected as a PCI card, but from the bus id I'd say it's a AGP card, is that true? In that case, it looks like the test for AGP/PCI doesn't work correctly.
In radeon_driver.c, it says "Following detection method works for all cards tested so far." Guess your card is the first it doesn't :-(
If that's the case, you can try to get it to work with "BusType" "AGP" in the XF86Config file.
Though I'd have assumed that a AGP card detected as PCI should still work.

btw, the "ForcePCIMode" option (which is only there for compatibility reasons I guess) no longer works (I just tried it out to test if a AGP card forced to PCI would work). It will set the card type to pci, but that gets immediately overwritten by the agp/pci test so the log file says
(**) RADEON(0): Forced into PCI mode
(II) RADEON(0): AGP card detected
I'd suggest just to remove that option, I guess there aren't really a lot of users using this, and those who do probably could figure out they should now use the "BusType" option instead.
