Not bad, I like the numbers here. This is definitely a good move.
I had long ago wanted to remove those legacy LED code in mach-pxa.

The down-side is that through these moves we've lost functionality each
time.  For example, the blinking heartbeat LED on the Assabet and
Netwinder which I always enabled to let me know whether the machines
were still alove has long since gone.

There exists a generic heartbeat LED trigger for that.  Making it the 
default for a particular LED should be trivial.
