I think the software is generic for this application. I think if the baseboard software does not work then you can use a workbench command that adds ram but I dont remember the command or the syntax.

I had a 1.5mb trapdoor expansion that connected to gary and required no software to work. I was probably on kickstart 1.3 at the time & I'm pretty sure the memory sizing in kickstart can cope with >512k at c00000.
 
Commands to add memory are usually only required for non auto config memory in the fastmem part of the address map. It might be mapped there, although I don't see why they wouldn't have connected to the CPU slot and gotten proper fast memory. You're having to open the case up anyway.
 
The extra memory might be disabled somehow, if it needs software to wake up the board then it'll be specific to that board. It might not be hooked up to gary correctly either. I used to have terrible problems with reliability as I also had a 2mb agnus with onboard memory that also hooked up to gary. Yes I probably should have bought an a500+.
