If it's not using a PC partition table; and I suspect it isn't, being a mac,
then it doesn't matter what partition type you use.

LVM2 doesn't even check the partition type - it's only for information.

There's no such thing as a numerical partition type in Apple partition
maps. cfdisk or parted could be used to create a different partition table
(precluding use of MacOS). Or LVM could be made Apple partition format
aware (using either a new partition type or partition name for detection;
I'd prefer the partition name (like, "LVM 1" etc. as that can easily be
added with mac-fdisk. (Creating other partition types is only marginally
more difficult, simply us 'C' instead of 'c' to create the partition).

To reiterate: I don't see any solution without making LVM accept Apple
partition maps in the first place. Which part of LVM checks the partition
type? Can you show me some sample code?

Stick 

#define __alpha__

at the top of tools/lib/pv_get_size.c and it will skip
the partition type check.
