[tlug] Firmware update breaks Flash player in Kubuntu

[Lyle H Saxon <llletters@example.com>]

I knew enough to avoid "firmware updates" from Brand-W (after being
badly burned) but still stupidly OKed a firmware update in Linux this
morning - which resulted in breaking Flash playback.  It plays, but in
wild florescent colors, such as 90% screaming red/pink with trace
amounts of other colors.

Two questions:

a) Has anyone else experienced this?

b) Can the broken Firmware update be rolled back?

The hardware is a 2006 IBM ThinkCentre box, and I'm running the most
recent LTS version of Kubuntu.
