Is this the sort of change we can consider making in a stable update?
I'm not at all sure, although my gut feeling is that it would be safe.
The 3.0 kernels in unstable (and testing?) right now have
XEN_MAX_DOMAIN_MEMORY=128, I think they use a more dynamic scheme for
this limit than the 2.6.32 kernels did too.
