Looks like the memory is there, but only first 8K at 0xfff00000 is writable.
Is it necessary to have the boot code up there?

Anyway after running your BPPCFix tool ("bppcfix install reboot") all of it 
becomes writable.
So then I can run gobsdppc a bit further. It now prints 
Booting Single-User...Using 32256K FASTMEM at 0x76000000, 2M CHIPMEM 
then resets the display and nothing more happens.
Which I guess is pretty much what can be expected currently.

32M in first slot and 4M in second slot:
Memory Address: $66000020  Size: $0237FFE0 (36351K)     Type=$00 CACHEABLE

4M in first slot and 32M in second slot:
Memory Address: $57C00020  Size: $0237FFE0 (36351K)     Type=$00 CACHEABLE

And one more: 4M in first slot and another 4M in second slot:
Memory Address: $47C00020  Size: $0077FFE0 (7679K)      Type=$00 CACHEABLE
