Is this with a debug=y build of Xen? I can see how that might provoke
the situation more than other builds.
Do you know how large a contiguous chunk the tg3 needs?
I guess we could hold onto a few large chunks before making the dom0
memory allocation.
Alternatively, if we get a failure, we should round up to the next power
of two and then balloon out that much memory. Repeat until success...
