Btw: if you use "--conout 2" with VDI mode and TT-ram, you notice
that TOS3 gives "infinitely" long ST-ram checking bar at TOS boot.

When memtop is 32k aligned, TOS3 detects TT-RAM, so I commited
that fix.


TOS3 + VDI mode doesn't work with new WinUAE CPU core although
it works with old UAE CPU core (or EmuTOS on TT emulation).
There's some mismatch between number of planes and resolution.

There's not much point in using VDI mode with smaller amounts of RAM.
VDI mode is used to get larger screen and that takes memory, with 512k
you don't enough memory left to run the applications.
