Same deal with a Samsung netbook that I purchased because of its semi-ruggedness (NB30). Out of the box BIOS was junk (ACPI problems, as usual, manifested as dropping keystrokes due to odd, periodic, momentary machine stalls), and the BIOS updater runs only under Windows. You can't even run the BIOS package (.exe) on another machine and manually extract the BIOS - updater recognizes that it's on a different machine and refuses to run.
Contacting Samsung was an exercise in futility. Tech support kept insisting I run the .exe and also told me that I needed to make sure that I installed the battery level monitor .exe beforehand. The tech support person could not grasp that I was running Linux, not Windows, despite my best efforts to persuade them otherwise. Unbelievable.
My mistake was not making this a dual boot machine, just to keep Windows around for such work. It's become standard operating procedure for me now to dual boot any machine that's likely to need a BIOS update (Dell, to their credit, is not one of these vendors). And with the tendency of vendors not to include CD/DVD restore media, I'll have to use some other install media to reinstall Windows just to perform what should be a simple BIOS update.
