Update to my recent post: I don't think it's necessary to alter the 
Windows rpc.cfg file at all, under RO4.02. Once I'd increased the VRAM 
values by a factor of ten (as suggested above by - AFAICR - Peter 
Howkins) I found that the Acorn AKF91 driver in use no longer 
defaulted to 256 colours when a display size of 1280 x 1024 was 
selected; in fact, it could support up to 16M colours!
