FWIW i still have gcc patches to fix that. They were first stalled
on copyright assignment and then on gcc's merge window being closed,
but now with 4.5 open for game I hope to resubmit them soon
again.

With that you can use -pg without frame pointer, but you have
to supply a special mcount function that expects the different
stack layout.
