FS-UAE "allocates" 2 GB memory at startup via mman, it does not use it, so you don't need 2 GB physical memory for this. Linux will not use actual RAM for the memory pages until the memory pages are used. Right now FS-UAE always allocates memory in a JIT-compatible fashion even though JIT is not enabled, so if it fails to reserve a large contiguous memory area, it will not be able to allocate Zorro III RAM.

(It is possible that with little physical memory, the system will be less happy to mmap large amounts of memory. I haven't examined FS-UAE's behavior in a low-memory environment).

You can attach FS-UAE.log.txt and I can at quickly look at the allocation log lines.
