I know it's generally bad form to reply to one's own posts, but for the
benefit of anyone searching the archives for a solution to a similar
problem I'll describe the resolution.

If you format the disk on the Mac you're pretty much on a non-starter,
although the Debian kernel config has "CONFIG_MAC_PARTITION=y" it won't
recognize the partition table  (does than only handle OS9 and below

Format the disk on the Linux PC and create a single partition at number 4
(remember ZIP disks?). Create an Ext2 filesystem on the partition, and add
a world-writable directory to it. Then provided you have the ext2 package
for the Mac (locatable via macupdate.com) you have disk that can be used
on both boxes.

The one thing I still don't understand is how the USB keyring whcih shoed
up at partition 1 was seen by the Mac.
