Ok. I'll try to update the howto and send it to maintainer.

The main difference is that new quota format supports 32-uids. There are
other minor changes - like root is no longer special user and such.
quotacheck speed relies completely on filesystem speed - quotacheck
has to scan all the filesystem. If you use e2fslib support on ext2 than
it should be reasonably fast but I agree that otherwise it's pain.
