> What address is the VGA buffer mapped to in V2 ?

It's not mapped by default in the linear space.  You can either access
it with the farptr functions or the nearptr functions.  Emulated linear
buffers (ie 0xd00xxxxx) are not supported.  Use the conventional_memory
selector with offset 0x0a0000.

If your video card has the capabilities of mapping a linear buffer in
extended memory, there is a VBE.ZIP example floating around which shows
how to turn this on and directly write to the card with both near pointers
and far pointers.
