I routinely create 4M domains (and I would be able to create them even
smaller if the domain builder would allow it), there is event a recent
Xen paper that mentions running ttylinux in this amout of space.

I think this is a problem in XenLinux, it was discussed recently, and
that you can 'fix' it by setting mem=16M on the linux command line.
