You run Backtrack in vmware/hosted on some other OS (like gnu/Linux).
or you use vmware with M$win to boot gnu/Linux.

And although I have no experience with vmware, (I use vbox) I thought to clarify this concept.
<edit> you might find it worth while to check the PCIID
of you devices to see if they have been documented and accepted into the gnu/Linux kernel. Generally on a gnu/Linux system and bsd types you can type "lspci" to see the list of pci devices connected to the system.</edit>
