FYI, further testing has actually revealed that 3.2.6 *does not* in fact fix this reliably. I can't say whether its "sometimes" or "always" with 3.2.6, as I think it worked at least once.. but the last few times, 3.2.6 is just like the precise kernel. 3.2.1 does *always* result in a trackpad that works.

More facts, I am booting into Ubuntu from rEFIt .. could it be part of it?
