Created an attachment (id=32950)
 --> (http://bugs.freedesktop.org/attachment.cgi?id=32950)
Full results of my speed test

Currently reclocking engine takes averagely .005152s. That's way too long.

Using Dave's patch I went down to averagely .000287s.
With registers patch went down to averagely .000267s.

Using both patches gave even nicer result:  .000185s.
Both + my patch hacked (to use "while" op): .000177s.

In every case corruptions were gone.

About hacked version of my patch, I switched to using "while" (just like
AtomBIOS does) instead of waiting in "for" for bit in 0x600.
