It seems that many people just want to do heavy overclock. And it can be difficult to detect a broken BIOS... though I've discovered an interesting method: when the customer support tells you to install crystalcpuid (a Windows utility) and then they reply that Linux is not a supported OS, then there are high chance that their BIOS is broken :-) There seems to be some comments on certain laptops giving overpower to Turions, but I can't confirm how many of them are real BIOS bugs. I will probably continue with this as an unofficial patch. Thank you anyway for looking into this.
