You can create the partition, and once it is written (while it is downloading
stuff, but before yaboot-installer is run), you go to console 2, and run
parted, and do a set <minor> prep on (try print to find your <minor>).

partman-prep has not yet been written, volunteers welcome to do it, look at
d-i webpage on how to gte the svn tree, and then look at partman-palo which is
quite similar to what we need.

Should not be needed, see above.
