That's what I expected (I probably wasn't clear enough that you only 
needed to grab the bootloader, not the kernel.)

Yeah more details would be useful.

I think we actually keep the display as it was in RISC-OS, IE we don't 
change what was working prior to RISC-OS.  At some point we might be 
more intelligent, eg try and read DDC info and make a mode from that but 
for now we rely on what was set in RISC-OS
