Hmm. Well, anaconda (Aurora's installer, taken from Fedora) won't even
attempt to do raid ops via parted without this patch present. It just
kicks back that there is a missing flag. With this patch applied, we're
able to create and use RAID1.

I'm not sure what sort of test case would apply here, as there really
isn't much "new" code. I'm not sure how Solaris handles software RAID,
so that might be an additional fly in the ointment.

Sorry, I know that's not much help.
