Widcom and Microsoft stack play nice?

[Kenundrum]

I've got the Integrated BT II in my t40 2373, but i've also got a usb dongle that supports BT 2 EDR. i can't seem to get them to play nice with each other since the ibm uses widcom 2.x and the edr dongle uses widcom 4.x. What i want to do is to have the integrated BT work with my mouse and to sync my phone/pda and then i want to be able to plug in the edr dongle for BT audio and stuff.
I figure that i'd try to get the internal running on the microsoft stack and the dongle running widcom and only being plugged in when needed. is that possible?
