I'm so sorry this languished for so long -- I don't see bugzilla mails
in my inbox, and it wasn't part of the driver, so I never saw the bug
report.

I've added more details to the commit message and pushed your patch --
it was definitely a good improvement over what was there before.  I
think the more serious problem is that we do copy propagation for the R0
to R0 assignemnt in general -- I think we're going to have actual
rendering bugs from that once I cook up a testcase.
