Great IDE perf (WAS: Strange PMAC IDE performance)

[Benjamin Herrenschmidt]

I tested on the iMac, and we have also the same register with the same
value. All three machines have the compatible property of the ide in the
device tree set to "heathrow-ata". I'm building a test kernel along with
other patches I made with a quick hack for this, I'll post it soon with
diffs so people can play with it and do real testings.
