I did no further testing after the onset of the Japan crisis, but I have just
started updating some relevant parts of my system.
Updating from kernel 2.6.38-rc8 to 2.6.38.2 did not seem to have an effect, but
updating Mesa to 7.11.0-devel (commit a26121f3) changed the observed behavior
in prboom-plus. The black melts are gone, replaced by transient graphics
corruption when starting a new game. This corruption fades within a span of
about 1 second, and causes no further problems.
In short, it looks like the problem was a combination of kernel changes and
Mesa support for my Radeon HD 5750. Apparently some changes to Mesa over the
past 7 weeks have resolved the problem I was originally reporting here.
