It's broken in a few ways. Unfortunately assigning it that label doesn't
change much... :)

No, it seems to have it right (if lacking details):
"41 PPC PReP (Power PC Reference Platform) Boot"

That's what I was afraid of... will that functionality ever happen? As
others have noted, whether we like them or not these partition types can be
important to various BIOS (the other example I just skimmed was someone's
APM depending on a RAM-on-disk partition iirc)...

I understand that it seems to break your model. :( Both personally (as a
user) and for an installer (which current uses only parted) I need to be
able to create these partitions. I can probably work around it, I just dream
of using parted all the time. ;)
