[PATCH] acerhdf: Limit modalias matching to supported boards

We got reports of acerhdf issuing warnings on Acer laptops other than Aspire 
Ones. Looking at the dmi match this sounds a bit to generic. IOW the module 
gets loaded on any Acer laptop. After the following patch the module gets still 
loaded on my Aspire One but not on the reported other laptop.
The same change might be helpful for the other two dmi matches, but I had no 
way of testing.

Subject: [PATCH] UBUNTU: 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. Probably the same change should be
made for the two other entries.
