I've got a Toshiba Satellite Pro 6100 with a Toshiba mini-PCI wireless card running 802.11b

I want to swap that for something like an Intel PRO/Wireless mini-PCI running 802.11g because that will immediately double my  download speed.  (I know because I also have a Dell Latitude D610 running that wireless card)

Anyone know if the Toshiba is compatible with that card;  ever done something like this; etc?

Thanks for the advice!
