A new cpufreq module, based on the ondemand one with my additional patches
just posted.  This one is more suitable for battery environments where its
probably more appealing to have the cpu freq gracefully increase and decrease
rather than flip between the min and max freq's.

N.B. Bruno Ducrot pointed out that the amd64's "do have unacceptable latency
between min and max freq transition, due to the step-by-step requirements
(200MHz IIRC)"; so AMD64 users would probably benefit from this too.

Add tg3_nvram_lock() and tg3_nvram_unlock() calls around tg3_halt_cpu().
It is possible that the bootcode may be loading code from nvram during
this call and stopping the cpu without getting the lock may cause
uncompleted nvram data to be left in the nvram data register. Subsequent
calls to read/write nvram data will fail.

On Nov 16 2004 a change to intelfbdrv.c was commited (as part of 0.9.2 it
looks like) that added __initdata to all of the module param variables that
seems to create the opportunity for an oops.

I've recently been chasing an OOPS
(http://marc.theaimsgroup.com/?l=linux-kernel&m=111552250920370&w=2) I
created by reading every file on the /sys file system and I've traced it
back to this code in the intelfbdrv.  Though I had root privs in my initial
problem report, it turns out they are un-necessary to generate the oops -
all you've got to do is "cat /sys/module/intelfb/parameters/mode" enough
times and eventually it will oops.

This is because sysfs automatically exports all module_param declarations
to the sysfs file system..  which means those variables can be dynamically
evaluated at any later time, which of course means marking them __initdata
is a bad idea ;)..  when they happen to be char *'s it is an especially bad
idea ;).

Applying the patch below clears up the OOPS for me.

Recent kernels occasionally trigger a PMU timeout on some mac laptops,
typically on wakeup from sleep.  This seem to be caused by either a too big
latency caused by the cpufreq switch on wakeup from sleep or by an
interrupt beeing lost due to the reset of the interrupt controller done
during wakeup.

This patch makes that code more robust by stopping PMU auto poll activity
around cpufreq changes on machines that use the PMU for such changes (long
latency switching involving a CPU hard reset and flush of all caches) and
by removing the reset of the open pic interrupt controller on wakeup (that
can cause the loss of an interrupt and Darwin doesn't do it, so it must not
be necessary).
