	Those were the latest available versions that I could find via
packages.debian.org.

	The machine is a Sony VAIO VGN-S150 laptop.  This machine was
decommissioned about two years ago when the keyboard inexplicably died.
Prior to that, it was running Debian 'unstable' on a daily basis just fine,
including GL acceleration.

	The keyboard just as inexplicably came back to life recently, and
I've been experimenting with various desktops as a prelude to gifting it to
my mother.  But then this corruption issue surfaced.

	It's a Sony, so I suppose it's possible the machine has traded a
broken keyboard for a broken graphics chip (is there a way to test this?),
but it has never been subjected to any abuse.  It also passes MemTest86+
without issue, so it would not seem to be a problem with flaky memory.

	The laptop in question isn't being used for anything (yet), so I can
subject it to any form of diagnostic abuse you choose :-).

	I wholeheartedly agree.
