Just a short question: The Kontron 986LCD-M appeared to be running
coreboot. Is that correct? Quoting from the failure log you sent earlier:

Apparently it finds the Kontron board just fine if the board is running

>From the above, I guess that Kontron detection fails if the board is
running classic BIOS. In that case, a verbose run of flashrom (probe is
enough) on a 986LCD-M with factory BIOS should give us the DMI strings
we need to match without problems even if coreboot is not running.

Thanks for the patch! Sean Nelson is currently working on a patch which
handles locking in a generic way, and I heard his patch is mostly
finished. Your patch is a good interim solution, but we'd have to revert
it once Sean's patch goes in (which may be even this week). Not sure how
to proceed.

Thanks. Given that we're currently rewriting probe to be more robust
(reset before and after probe), and Sean's locking patch is just around
the corner, everything will need to be retested. I plan to commit your
patch if those rewrites are not committed until early next week.
