This is where I use xmon. There is a macos version at (I think)
ftp://ftp.linuxppc.org/users/paulus/misc/xmon.bin. From memory, the
control registers are at 0x90010000 and the RADACAL (ramdac/cursor
chip) registers are at 0xf301b000.
The other thing to do is to browse through the darwin sources from
apple and see if they have a control driver somewhere.
IIRC, the hardware cursor uses some extra bytes on each scan line and
some registers in the RADACAL.
Paul.
