According to the model support page and a dev / ls listing I found*,  
that should be

/bandit/ATY,mach64_3D_pcc not ppc.
If that doesn't work, try /@F2000000/@11

How gracefully OF handles things like this is version dependent. If  
you give it an invalid device name it may just croak.

I think only the VGA port is activated, the Mac DB15 video port  
isn't, but its been years since I touched one of these and my memory  
is fuzzy. I'm not sure about the PS2 keyboard connectors, I doubt OF  
would know about them. You might be able to output to the ATI card  
and input with the serial console if you dont have an ADB keyboard.

Search the list archives or NetBSD.org from the main page, I'm sure  
somebody has one. If not that, google.
