I had a quick look at the fadt.c and it looks good!

The TODO you added is also a known problem, but i think it's not a big 
But i also can't say if this will disappear if you turn off acpi-debug, because 
here it's enabled too.

This time i added a diff on my acpi tree of cb to the acpi_tables.c file.
You also *need* the DYNDATA generator to get PowerNow working.
Have a look on that, it *should* work, i don't know it exactly, because it's a 
few weeks over when I experimented the last time with this code.

I think the essential part of the diff is this one:
+       /* DYNADATA */ /* used by the PowerNow! generator */
+       acpi_create_ssdt_generator(ssdt, "DYNADATA");
+       current += ssdt->length;
+        acpi_add_table(rsdt, ssdt);

Hopefully you'll get that with my comments. :)

Kind regards,
