Remap [Function] key on a Gateway laptop

Since the motherboard on my HP laptop died, I'm temporarily using my wife's Gateway laptop. It's a nice little computer, except the [Function] key is at the bottom left of the keyboard, where the CTRL key should be, and the CTRL key is next to it. I know that the [Function] key is not interpreted by the OS, only at the hardware level, so is there any way to switch these keys? Having the [Function] key there is SO unnatural.
