acer_wmi kernel module is prevent of correct work of Acer Aspire one 721-148ss.
For example if this kernel module is loaded it's not possible to enable WiFi.
First bugreport here: https://bugs.launchpad.net/bugs/791373
Blacklisting of acer_wmi solve this problem. So probably acer_wmi is doesn't
support of Acer AO 721 (or have support, but this support is buggy).

I also want to note, with 2.6.35 kernel I have only one problem with acer_wmi
https://bugs.launchpad.net/bugs/683979 (it's not my bugreport, but I have
exactly same problem with 2.6.35 kernel on Acer AO 721).

Decompiled DSDT table of Acer Aspire one 721-148ss attached.
