Comment 10 for bug 8497

Pondering a bit about the bug I thought about using the linux real mode
interrupt (lrmi) interface (that vbetool already uses) to figure the bios driver
order. The interessting bit here is int 13h/ah=48h
( to get drive information. I wrote some
testcode (based on vbetool) at Calling the interrupts
works pretty well but I seem to be unable to get the drive information into a
real-mode buffer :/

Another idea would be to use the partition label or uuid to figure the
boot-partition but that would involve a lot more work than the rather simple
approach above.
