Unfortunately the stock video options (ATI FireGL X1 and X3) give an incredibly slow unaccelerated 2D due to failure to kickstart the command processor (radeon open source driver). Neither folks from linux-parisc@ nor from dri-devel@ camps know how to fix this.

If memory serves PA-RISC had some restrictions on PCI BAR windows, it
wasn't just endianness problems.
