I'm afraid you will have to taint yourself with GPL code and look at the
Pegasos platform fix in the latest kernels for the Via IDE stuff. You
need to do a little tweak or two to get it to work in native mode properly.

Otherwise, though, the damn thing works fine in legacy mode, just use
interrupt 15.. you'll find it works really well.

Remember the OF device tree is broken and reports the wrong interrupts
(0x14 and 0x15 instead of decimal) - there is a device tree patch at
http://www.powerdeveloper.org/platforms/pegasos/devicetree
