No valid timers found on ALIX (was Re: 9.0-BETA2 - Kernel Panic on ALIX)

Just to clarify for Edgar,

His 9.0 build isn't finding any valid timers; hence why the thing
panics upon boot.

Since I've got a few Alix boards I'd like to use for 11n testing, i'd
like to know how to make this work.
Does anyone know the relevant magic to see which timers are available,
and force enable something that'll work?
