Having exact same issue with Acer Aspire One D150 (Atom N280) with latest BIOS 1.11 of 2009/09/21 (guess you have D250 as BIOS 1.15 was released for that machine same day). Now this is with Arch Linux, so it's probably offtopic OS too, but as this seems to be the only thread on the net with any activity on this issue I hope you get an answer from somewhere...
