This is nice :) Seems to work for me based on a quick test
on at least omap36xx.

Looks like n900 produces the following though:

core: _opp_supported_by_regulators: OPP minuV: 1270000 maxuV: 1270000, not supported by regulator
cpu cpu0: _opp_add: OPP not supported by regulators (550000000)

But presumably that can be further patched. So for this
patch:
