Comment 13 for bug 330606

OK, I hope this helps someone who comes back to this bug...mostly because each person who is helped by this will make me feel less stupid. :)

Anyway, if you're having this problem on an Acer Aspire One, and the modprobe.d info from Ralf doesn't help, try hitting "Fn-F7" (ie, hold down the "Fn" key and press "F7". It's a key combination that toggles the touchpad, and I guess it gets saved to the Aspire's NVRAM or something because it definitely survives reboots/shutdowns.

Watch out! It's right next to the mute ("Fn-F8" :p).
