SRU Justification:

Impact: When the acerhk module is loaded on non Aspire One systems it will 
issue a warning about finding a bad/unknown BIOS version. It will not load and 
there is no bad effect, beside users getting scared.

Fix: Limit the modalias to only boardnames starting with AOA

Testcase: Booting on Aspire One still loads the module, other laptops don't see 
the warning anymore.

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

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

Upstream status: acked, but not accepted, yet

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. Probably the same change should be
made for the two other entries.
