I tested gpart on pc98 and found some problems.

1. A disklabel checking in g_part_bsd_read() is failed.
2. g_part_pc98_dumpconf() does not print a slice name.
3. g_part_pc98_probe() is too strict.
4. It's failed to recognize a big SCSI disk as BSD slice.
5. A (bit strange) FAT slice is recoginized as BSD slice.
(6. Do we need more work for libdisk?)

I fixed 1, 2 and 3.
