Peter,
Having just upgraded my AOA150 to 2.6.32, acerhdf was complaining:
acerhdf: Acer Aspire One Fan driver, v.0.5.18
acerhdf: unknown (unsupported) BIOS version Acer/AOA150
/v0.3310, please report, aborting!
DMI reports the product as "AOA150 " (i.e. 9 spaces after the
6-character model name). This causes the product match to fail, so I
had to use force_product="AOA150".
acerhdf: Acer Aspire One Fan driver, v.0.5.18
acerhdf: forcing BIOS product: AOA150
Then all was happy again. Any chance you could strip leading/trailing
whitespace in the product match to avoid this issue?
