I've just pushed out the initial evergreen (radeon HD5xxx)

you'll need 2.6.35 with kms enabled. There are still some GPU hangs
in some cases that we haven't sorted out yet. Richard will be pushing
out mesa support as soon as he finishes rebasing his tree against mesa
master. We'll be releasing updated register specs eventually, but as
you can see, most of the registers and bit fields are the same as
r6xx/r7xx. Happy Hacking!

Crashes for me when the boot scripts start 'xdm'. Attached tarball has
'dmesg' output, copy of 'Xorg.0.log', and copy of 'xdm.log' (with same
backtrace as Xorg.0.log).
Should I put this on Bugzilla, or is evergreen-accel too new?
Hardware:
Radeon HD 5750
Software:
linux 2.6.35.2
[merged with drm-radeon-testing merged up to c9f9e91; have also reverted
5b1714d, and added patch to fix pink vert. line -- not sure if there are
git commits available yet]
libdrm 2.4.21
mesa 7.9-devel, git be99100
Hmm, I was just looking over the build log for Mesa that I saved. Not sure
if this has to do with the crash, but when I followed the warnings to the
code, this looks potentially disastrous:
r600_cmdbuf.h:201:63: warning: backslash and newline separated by space
r600_cmdbuf.h:202:79: warning: backslash and newline separated by space
Here are the offending lines:

Looks like a bad place for escaped newlines to fail, but if this was
really the problem, wouldn't the compilation have failed instead?
