I suspect there aren't any drivers available, but even if there were the Squirrel probably wouldn't fit in. Unlike the Amiga, laptop PCMCIA slots take the entire card, and the Squirrel has been designed so the portion of the card that doesn't fit inside the Amiga is wider and rests on the desk (to stop you breaking it, and it probably holds some electronics too). It's much wider than two PCMCIA cards, so it wouldn't even fit in the top slot on a laptop.
