NAK.

An equivalent patch to this was submitted to the ACPI tree two days ago (which 
blacklists both the known Aspire One DMI entries) and is now upstream (and 
will also be backported to the next stable release).

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=a74dd5fdabcd34c93e17e9c7024eeb503c92b048

(The Aspire One is special as, unlike other Acer laptops which are 
unsupported, it provides the ACPI-WMI inteface we're trying to match on, so it 
really does have to be blacklisted - so WMI matching won't help in this 
particular case).
