I would hope that a patch that _only_ prints [Firmware bug]
should be enough.  This isn't the kind of workaround
that we should really have to carry in the kernel.

This is still a very new platform, and my guess is that
they are actively updating the BIOS as we speak.
I'll see if I can figure out who to talk to
in order to make sure of that:-)
