d-link wireless card

i'm helping a friend with his computer, and i just set up a dual boot tonight (win-xp and mandrake 10official)... we're running kernel 2.6, gnome 2.4, mandrake obviously, and it's a p4 1.6ghz system made by vpr-matrix (the bestbuy house brand)... i'm guessing it's an intel motherboard, infact i'm pretty sure it is.

anyway, we just recently put in a pci wireless card (D-Link DWL-520 802.11b : link) and it works fine in windows xp, obviously, but not with mandrake... it wasn't one of the ones i could choose from the menu during setup (and i don't really know the chipset or what-have-you to figure out which choice it may have been if indeed it was on there)...

so basically, i'm wondering if anyone's ever used this card with linux, especially mandrake and/or the 2.6 kernel, and know's how to set it up and can help me, cause i'm not a linux/unix genious, i just love the os, and know some stuff about working with it, but not crazy coding or anything... i'm into hardware, not programming.

please help! my friend really wants to try linux, but the internet is sortof necessary for him to utilize it to it's full extent, because you can't switch if you can't do everything in linux that you can in windows, and the internet being inaccessable is a pretty huge setback.

thanks in advance,
