Perhaps this page entitled "Using the DWL-520 rev. E1 with HostAP"
might be of some use to you:

I found it on the HostAP-related links section of the HostAP homepage.

A tantalizing tidbit from the page:

    All is not lost, however. Don't return the card or chuck it. It
    will work using the HostAP driver.
