Good!

Thanks. As you know, it's difficult for me to test ;-)
Actually, there's an iMac here that I can probably hijack... ;-)
Changes I've made:
* Apple_Free partitions now have status 0x0 (not 0x33)
* won't zero out bits it doesn't understand in block 0, anymore
* now preserves the driver signature
That handles all-but-one of the diffs. I have no idea about the last
remaining one (it's in the pad field...)
I can't upload to ftp.gnu.org yet (still waiting for kerberos, arrgghh!)
