Can anyone/does anyone see any problem with this ?
I have this running for about a week now. (UP and SMP)
Discovered on one lappie of mine when X video driver was running on the 
same IRQ.
Also reduced problems on 2.6 SMP/PREMPT box (further probs I don't think are
being caused by prism54; well early stages yet - smp/preempt/wlan eek.)
If no one shouts, I'll commit and push to Jeff; I think this should be in 
2.6.8 final.
