Well, the problem is present in the -1ubuntu4 build also, and the build log
for that version (built on Mar 2) shows that gcc-4.3 4.3.3-5ubuntu1 was used
for the build, postdating the fix in 4.3.3-3ubuntu4.

I was guessing that this was simply a case of the seemingly-innocuous change
exposing a bug elsewhere in the code, possibly a bug that upstream has
already fixed.  I have it on my todo list to build the latest upstream and
see if the bug is reproducible there, but I understand this depends on
having a bleeding-edge libdrm first - I was waiting for a new upstream
version to be uploaded to jaunty, but Bryce says even this may not be new
enough.  Bryce, do you have a pointer to the upstream git for libdrm?
