Ok, so fdisk doesn't do this any more. But does changing the BIOS
geometry in fdisk actually do anything (haven't looked recently)?
I suppose not. After all, how would you communicate the changed
geometry back to the BIOS?
Note also, that some BIOSs do exactly what I described for our fdisk in
order to deduce the geometry of a disk. Those happened to hang with our
old method of using the complete disk for NetBSD (i.e. no MBR partitions).
