Prism 2/2.5/3 devices are supported; however, just because a vendor claims
it's a Prism chipset does not necessarily mean you're getting what you
expect. D-Link is a good example; they had a working card based on the Prism
chipset, and then changed it so that the wireless driver was required to
flash some firmware (which only worked under Windows; wi(4) didn't support
that kind of behavior), and then changed it again later to an entirely
different chipset (see message from millert@ a day or two ago).
For best results, pick something off of i386.html (if that's your platform),
then double-check that model in the archives (double-checking before I
purchased my DWL-520 would have saved me some trouble; only hardware
revisions A & B are supported with wi(4)) before purchasing.
(however, if it really is Prism-based, you'll /probably/ have no trouble.)
I'm sure Todd or someone else can give a more authoritative answer.
