Multiple wireless cards in one laptop

I'm running XP Home on a Dell laptop w/integrated G wireless and a PCCARD Linksys G card.

I'm wondering if it is possible to "bond" the two wireless cards to increase my throughput in my home network for file transfers, etc. (I already know that it ain't going to do squat for internet, one card is already faster than that).

Home net has three file servers on a 100 Base-T hardwire network, and a Linksys wireless G router.

If possible, how? Additional software? Or 'tweaks' in networking?

I'm nowhere near a newbie when it comes to this stuff. But after a Google search(many, actually), I have not found anything to do with this particular situation.

What I'm looking for is something along the lines of the old modem bonding trick.

 

No, but you can bond two different networks together by using the Laptop as a bridge.

 

Wireless, or wired, it can Not be done with regular network cards and client OS.
