The problem is similar on ST, where the allocated screen memory is 
always 32 kB. Not enough for extended resolutions.

IIRC, Thomas said that that he used a very clever trick to allow 
extended resolutions. Since the screen is always at the very end of the 
ST-RAM, he just artificially extends the ST-RAM to fit the extended 
resolution requirements. Very simple and efficient.

Hatari should use the same same strategy for Falcon extended video 
modes. The situation is similar, anyway.
