Yes.

SeaBIOS already does that. (SeaBIOS doesn't parse the bootorder file
- it generates a "glob" like pattern for each device and then sees if
that pattern matches a line in the bootorder file.)
Also, I don't have a strong objection to Laszlo's SeaBIOS patch (the
one that does the runningOnQEMU() check). (I still think it's quirky
to use bus-id in the file, but it's not a show stopper if it's just
for QEMU.)
