Running two wifi cards in a tablet at the same time....can it be done

I am looking to put two wireless adapters into a PC tablet computer and configure one in an ad-hoc mode and the other to infrastructure. The two would be allocated to two different channels. Has anyone already done that? Anyboday know if that can be done? I am looking to do that probably with an embeeded WI-FI card as one and a Cisco WI_FI card for the other.
