I've seen the voltage drop to 0.976V under LinX load. 
Still stable thus far. Doing a 5 hour test with OCCT before I officially pronounce it stable

Stable on a 24-hour Prime95 Blend run, but fails a LinX 100 run (10,000 problem size) at number 92. Might've been a bit too ambitious with 1.05V.
Bumped the voltage to 1.08125V in the BIOS, results in 1.008V under LinX load which seems stable (passed the 10,000 problem size 100 run, currently testing 13,500 problem size 100 run after which I will declare it stable). Load temperatures are about 1C higher with the increased voltage.
Still, not too bad
Impressed that the Q6600 can go from 1.25V to 1.08125V and maintain stability. Might drop the voltage back to 1.05V for general usage, as 1.08125V seems to only be required for LinX.
EDIT: With the decreased voltage I was able to remove the 80mm extraction fan at the back of the case (which generates quite a racket) and still maintain acceptable temperatures (69C highest core during LinX, which is still better than the 71C it reached during Prime95 with stock voltages and the extraction fan). It's now almost inaudible
