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
