Actually, what would be perfect would be to use the configuration that
the BIOS sets at boot by default.  That is device-dependent, however.

It is, but it can be read out either by INT calls at initialization 
time, or by reading out the byte at physical address 0x417:

I should have said "arch-dependent".
I didn't mean it wasn't possible, but just it'd probably be better that
driver experts do it, not me :)
