Just reduce the 1600 to 1440, as VRPC will use the PC mode of the same 
resolution, and ignore the actual timing information.

You will have to change to using the ARM7500 emulation, as the StrongARM 
one emulates the limitation of 2MB of VRAM of the Risc PC. Where as the 
ARM7500 stores the screen buffer in main memory, so as long there is 
enough main memory you can do as big a screen as you like. The 
resolution you are after will take 15MB.
