Note: the ahci driver has lba48 support. The Mach interface is still
limited to 32bit sector count, however.

The current Linux ide driver only handles LBA28, i.e. 2^28 sectors = 128GB. Sectors above can't be reached by GNU Mach, LBA48 is needed for this. That means checking that the drive supports it (should anyway), and just use the LBA48 versions of read/write. That should push the limit to 2TB, since sector numbers are stored as unsigned ints
