This was with the latest Intel mesa driver on an Ironlake laptop.
However I got a random crash on a previous run, I'm guessing if we can
figure out the misc crasher we'd be in a lot better place.
Great to hear; indeed, if the crash could be sorted out, and I could
have a look at the test failures (copy the results page) then we could
whitelist it; very much looking forward to this.
I would then need to know what you think these whitelist criteria should
be (does this depend only on the intel driver version, or does it depend
on the particular Intel chip and/or on the versions of other packages).
About the crash you're getting, have you tried MOZ_X_SYNC=1
MOZ_GL_DEBUG_VERBOSE=1 firefox with a debug build from
http://ftp.mozilla.org/pub/mozilla.org/firefox/tinderbox-builds/mozilla-central-linux64-debug/
Though this probably doesn't have symbols, you can at least get a good
JS stack by calling DumpJSStack() from GDB (prints into the terminal
that _firefox_ is attached to).

5. A few Firefox debugging infos/tips that you may find useful:
- when using OSMesa, the whole WebGL conformance test suite runs without
any legitimate valgrind errors [4].
- defining the MOZ_X_SYNC env variable enables XSynchronize
- when using a debug build of Firefox, defining MOZ_GL_DEBUG enables a
special "openGL debugging mode" that calls glFinish() after every GL call,
that checks that then OpenGL context that a GL call is supposed to apply to
is indeed the current context (or else it aborts), and that logs GL errors.
MOZ_GL_DEBUG_VERBOSE will log every GL call.
- debug builds of Firefox may be downloaded from
http://ftp.mozilla.org/pub/mozilla.org/firefox/tinderbox-builds/mozilla-central-linux64-debug/
but they don't have debug symbols AFAIK. For that, you may need to make your
own build [5].
- to run firefox in GDB, do firefox -g. When attaching GDB to already
running firefox, attach to firefox-bin.
Cheers,
Benoit

Sample query for all crashes in r600_dri.so in Firefox 4 ("branch 2.0")
that are NOT caused by a plugin like Flash during the past week (the low
volume of crashes is explained by the fact that we're not whitelisting this
driver so only the few people running with MOZ_GLX_IGNORE_BLACKLIST are
exposed):
http://crash-stats.mozilla.com/query/query?product=Firefox&version=ALL%3AALL&platform=linux&branch=2.0&range_value=1&range_unit=weeks&date=01%2F16%2F2011+18%3A05%3A19&query_search=signature&query_type=contains&query=r600_dri.so&build_id=&process_type=browser&hang_type=any&do_query=1

[4] See:
https://bugzilla.mozilla.org/show_bug.cgi?id=588918
To anyone wanting to reproduce this, you need a recent Mesa (post bug
31837), a build of firefox with --enable-valgrind --disable-jemalloc, and
the valgrind suppressions file given on bug 588918.
