I don't remember the details, but iirc you cannot convince OFW to
recognize FAT partition on a disk that has apple pmap.  Or may be you
need some arcane knowledge...  But since Apple's OFW is mostly
stripped, you cannot "see".  The disk must be plain, boring MBR.  Make
sure there are no residual traces of pmap.

IMO, if you don't need to dual-boot with MacOSX and your OFW
recognizes MBR/FAT, just stay away from pmap/HFS.
