if I try including nouveau in the kernel and rebooting into that kernel, I get this message:
power button [pwrf]
acpi: requesting acpi_cpufreq
tsc; marking tsc unusable due to tsc halts in idle
acpi: invalid active0 threshhold
thermal lnxtherm:00: registered as thermal_zone0

and the boot just hangs there, If I remove nouveau everything works fine

thanks

It looks like an acpi problem. Initializing the nouveau driver
at that point is coincidental. Ie, acpi is waiting for some probe
to return information, the kernel pauses it to handle a notification
from the nouveau driver, and somehow acpi never restarts
(missed the probe return, still waiting when the nouveau
driver finishes its initialization). Missing lock?

Try some different kernels.

I've tried my machine's kernel, and a different kernel
non nouveau kernels boot
others just show the same error message
an initrd wasn't helpful either

mm... I think nouveau still doesn't have power management code. Could be this the reason if you're trying it to force something it doesn't support.

There is a linux-acpi bugzilla and mailing list. You might search either for
mention of nouveau to see if anyone else has reported a similar bug.
You can also search for mention of your mb, mb chipset, BIOS version,
etc, in the context of acpi.
