Not very complex, timeframe is approx 3 weeks (ie once I have got the basic
USB working to make the GUI usable and then begin to port the rendering engine
to RTEMS. Audio will be needed too).
The PFPU and TMU2 hardware documentation is available on milkymist.org, and
for the API you can have a look at the existing drivers in libhal
(software/include/hal/{pfpu,tmu}.h; software/libhal/{pfpu,tmu}.c) and just
adapt that to POSIX (ie through an entry in /dev).

It's a major time sink and there is no timeframe for this. Eventually I'll
just make input devices (keyboard + mouse) working on 1.0, with the input
device protocol implemented in the AVR and a simple AVR->LM32 protocol in
order not to have to implement every USB idiosyncrasy nor face other
complications with the RTEMS USB stack and RTEMS USB input device drivers (or
rather lack thereof). If someone wants other devices to work (USB sticks,
bluetooth adapters and what not), then they make the OHCI firmware and drivers
themselves. Let's put that on more shoulders...
