AFAIK, there is no work on a Linux port to the O2. There is, however, a
NetBSD port.
In any event, with any port, it will probably not have graphics. I have
asked around about getting documentation on the O2 graphics and it looks
like that is imposible. It just doesn't exist. And to make things worse,
with the O2 architecture, apparently if you pass in values to the graphics
board in the wrong order (even if they are the correct values), the board
can fry itself.
The dmedia capabilities of the o2 will be really hard to get working under
Linux due to the lack of real time extensions and guaranteed I/O in the
kernel -- not to mention lack of documentation for the hardware.
The O2 is really a one off product that resembles very little any other
SGI architecutre. There is a port to the INDY, Idigo 2, O200 & O2000, but
I am doubtful of a good o2 port any time soon.
Sorry I could not be of any more help.
