PATCH: enabling power mgmt on G3

Hi all,

Is there any reason for not enabling the 'Dynamic Power Management'
feature of the G3/G4 processors under Linux?

OK, the firmware might already have enabled it, but that will not be the
case for 60x machines upgraded to G3/G4.

Anyway, here is a patch that backports the specific G3/G4 feature
enables out of 2.3's head.S and adds DPM. It also re-enables speculative
adressing, since some INIT's under MacOS disable it to work around
problems in the ROM.

It didn't crash my machine, but it might crash yours.. so test with
care, and report back to me!

Have fun

Michel

PS A similar patch for 2.2/2.4 kernels should follow as soon as I get
those to boot with my IDE card.
