That's interesting. This command does write to the chip without erasing
first, so the image you now have in ROM is supposed to be a mixture of
the old and new BIOS. If you haven't tried rebooting yet, I'd advise
caution.
Please try to verify the image you just wrote before rebooting.

Yes, known quirk, will be fixed in the near future.

Ouch. That would be a regression in Linux. Have you tried to report this
to the linux-kernel mailing list?
