How about trying the RomTagMem program (I think it is on Aminet somewhere). 
I never did use AutoXA while I had my A1200-system.  RomTagMem was better in
some ways.

The PCMCIA port takes up the last 4-megs of address space, so unless the
M1230XA was smart, you might be screwed.  In other words, 4 megs for RAM
expansion, 4 megs for PCMCIA, then more room.  I could be wrong here.
