I suspect this is a buggy bios, since that sector count comes from
a bios call done during system initialisation.

'sysctl machdep.diskinfo' should report the values being used.

Maybe fdisk should use the disk size from the 'netbsd geometry'
as the limit for the partitions.

1.6.2 does no validatoon on the numbers at all...
