So gpt could be the other exception because it is backward compatible with
msdos labels (to some extent).
But please let's not make a general rule out of this. The chainloader is
an implementation of the DOS MBR<->PBR boot protocol, which has been mimicked
by others but is still only available on msdos labels. If someone tries it
on another partition label type, she should see an error.
Btw, does this bugfix depend on the rest of nested partition changes?
