1. Under Linux, there are no problems putting filesystems on the
whole-drive devices.
2. Linux ignores the head/cylinder/sector portions of the partition
table, and only uses the relative start and length fields
(which are 32 bit sector counts), so you can have partitions
on a disk which are out of range with repsect the the HCS
mapping although you can't boot from them.
