For instance, if a Fedora 12 install doesn't work without 256M, that's a solid argument to bump the allocation.  Short term, I'd like to see this globally configurable.

I keep a patch in the SUSE version for quite some time now that bumps the default to 384 for qemu-kvm. That was the first "round" number where an openSUSE installation worked.
