Brief update: Tweak is still necessary with the Precise default kernel, but the final 3.3.0 kernel I tested under Oneiric was OK.
Looks like there's some upstream work in the area of buggy AMD motherboard BIOSes: https://lkml.org/lkml/2012/3/28/249
If you want me to try for a bisect I can do it; although is it needed if the latest upstream is alright?
