Resending the patch (yet again). Len, please? I cannot see a reason this
cannot be taken...

Subject: [PATCH] acerhdf: Limit modalias matching to supported boards

BugLink: https://bugs.launchpad.net/ubuntu/+bug/435958

The module alias currently matches any Acer computer but when loaded the
BIOS checks will only succeed on Aspire One models. This causes a invalid
BIOS warning for all other models (seen on Aspire 4810T).
This is not fatal but worries users that see this message. Limiting the
moule alias to models starting with AOA or DOA for Packard Bell.
