Did you try rc_fast_and_loose=YES in /etc/rc.conf ?

UVM and UBC are larger, for example, but they have shown a real improvement
on low memory machines for me (despite the fact that the kernel is
larger).

gcc is also to blame here, gcc-2.95.3 needs much more RAM and CPU than
the 1.4 egcs used. Some work is supposed to have been done in gcc3 for this.

maybe the vm.* sysctls needs some tuning for low-memory machines.
