You could add a min_ram field to QEMUMachine along the lines
of the max_ram patch I submitted earlier this week:
 http://patchwork.ozlabs.org/patch/87807/
and then have vl.c clamp the default RAM size to be at least
the minimum.

(I actually thought about implementing that in the patch but
I didn't have a use case for it at the time...)
