Right, that particular bug wasn't related to TT-RAM, just VDI mode.

For me that change fixed it for this:
$ hatari --conout 2 -s 4 --machine tt --tos tos306uk.img \
  --vdi-width 640 --vdi-height 480

But it doesn't appear to work for all sizes.

I tested a bit more and TOS3 memory detection tests work if correct
memtop & phystop sizes are used.  For older TOS versions the gap
must be 32k though, otherwise they don't boot.

I commited better fix.
