Honestly, I don't know. I've never tried LVM on PowerPC.

So you do indeed need to keep the original partition format. Without Apple
partition support in LVM, you could always try a sick hack: Add a PC style
partition table to the disk (they can, in fact, coexist, that's how dual
PC/Mac zip media are done). Make sure the partition maps match exactly,
and use the 0x8e partition type in the PC style table. AFAIR the kernel
does first probe for PC style partition tables, so it should work both
This hack is not for the faint of heart, and I cannot stress enough that
you need to have a backup of your partition maps (the first few sectors of
the disk), as well as a method to restore the maps (booting from floppy,
or some such, with another floppy holding the backup) before even
considering such a hack. If the above doesn't make sense to you, please do
not attempt to force it.
