RAM configuration tricks on A/UX?

Does anyone know any trick for violating the MacOS RAM configuration
rules when running A/UX?
More specifically, we have a number of A/UX machines with 4 1 Meg
simms. A/UX (with networking and X) runs much better in 5 Megs than 4.
On MacOS the only memory expansion we can do is add 4 more simms,
either 256K simms or 1 megs simms.
Neither of these options are attractive. 4 extra 1 meg simms per
machine is more than we can afford. On the other hand investing a lot
in 256K simms is wasteful, since they cannot be used if more memory is
added later.
I wish there was a trick that let us just add a 1 meg simm to the 4
already there. Every Unix kernel I have seen (prior to A/UX) has been
very flexible on sizing memory. I don't know what the real issues are
on the MacII, but at the very least MacOS will not boot with 5 1 meg
simms, which gives no way to boot A/UX.
