Ok, the problem is that I don't have multitouch support because the
bcm5974 module is not being loaded.

The output of lsusb -t shows that usbhid is handling the trackpad:

A few weeks before I've builded a custom kernel from upstream, the
3.1-rc7 version with those config params as I wrote earlier and
multitouch support worked like a charm.

I've tried loading the module with "modprobe bcm5974" but nothing happened
