Hi Alan!
Thanks for the info

Yes, but a new video-card or Motherboard can be easily bought (although it costs), but the data on a locked disk is lost forever, unless you pay for professional recovery (which is also a time-issue, if time critical data is stored on the disk). Of course, this can be solved with a good backup strategy...
I agree with you though, that this really isn't a kernel issue, but a BIOS thing. Distributors should/could provide additional security by freezing the security-features early during boot, until BIOS vendors do their homework.
regards, Jonas
