Please stop the FUD Bruce.
First of all, this is no longer architecture dependent. You can
use MBR's on your sparc64 if you for some reason feel like it.
Second, the names follow what is on the disk.
If your disk has only a BSD disklabel, then the names will be
constructed by appending a single letter and we get:
${disk}[a-h]
If your disk has an MBR, then the slices are named by appending
"s%d" so the names become:
${disk}s[1-N]
If you put a BSD disklabel in one of the slices, the name
will still be constructed by appending a single letter, so the
names become:
${slice}[a-h]
or if you like
${disk}s[1-N][a-h]
