No, lvm could be added to partman in no time, but Colin Watson voted against
this, and rightly so, since he claimed that we should not use a quick hack,
but come to a consensus on the way of doing this with both the d-i team and
the lvm-config tools (also upstream probably), for future portability issue.
Nobody did really find the time to push this, and thus there is no lvm support
on powermac (altough there should be no problem on prep and ibm chrp hardware,
and i have solution for pegasos too).

Ok. The main problem is that there is no LVM flag for mac partition tables, i
wonder how usefull that is though. Parted is a bit shaky on this, as i believe
it should not really be a partition flag, but a partition type.
