Hello,

I just started with NetBSD 2.0 on an Ultra 10 ( Thanks Michael! ) - 
works fine so far - and had a look at XFree86, mainly to get the 
onboard ATI Rage to work. After some fiddling I got it compiled just to 
find out that it expects wscons and sparc64 apparently doesn't have 
that.
To overcome this I did a quick but hopefully not too dirty port of 
macppc's ofb driver - basically a dumb framebuffer driver which gets 
its information from OpenFirmware - surprisingly I got it to work 
without too much hassle. It should work with any PCI framebuffer 
supported by OBP, with some (probably minor) additional hacking it 
should also work with SBus devices.

Here's the kernel output with some debugging info...

this gives:
- faster output
- different fonts ( well, at least we can compile in different fonts, 
loading them at runtime doesn't work, but it's unsupported on macppc 
too )
- colour if we want that
- proper terminal emulation.
Now my question - how much work from others did I duplicate? ( well, 
this hack took 2h or so, most of the time spent getting used to 64bit ) 
How much work would it be to make keyboard and mouse wscons-friendly?

After that XFree86 should be fairly easy.

have fun
