I would like to upgrade the internal card in my R51 to one that is capable of N speeds. I don't want to use one of those USB or Cardbus slots because I'd like to use the internal antenna (I just replaced it). This thinkpad uses the Mini PCI Standard, and I've had a hard time tracking down N wireless cards that aren't Mini PCI Express. Are these two standards compatiable? If not does anyone know of a wireless card that would work for me? Also I've heard something about Lenovo/IBM whitelisting their cards, so that the BIOS won't boot unless its an Lenovo/IBM card.
