Linksys WMP55AG PCI

Hello All,

I recently purchased a PCI-based Linksys WMP55AG card, in large part because it
was listed as supported on http://www.linux-wlan.org/docs/wlan_adapters.html.gz.
Much to my chagrin, however, I've been having some real trouble getting it up
and running so far, and I'm hoping that someone here can help.

Using linux-wlan-ng-0.2.2, I was able to successfully build prism2_pci.o for my
kernel, along with all of the other supporting modules. However, when the system
tries to insmod prism2_pci, I get:

Using /lib/modules/2.4.22/net/prism2_pci.o
/lib/modules/2.4.22/net/prism2_pci.o: init_module: No such device
/lib/modules/2.4.22/net/prism2_pci.o: Hint: insmod errors can be caused by
incorrect module parameters, including invalid IO or IRQ parameters.
      You may find more information in syslog or the output from dmesg

dmesg isn't particularly helpful; in fact, I see only one line related to that
module:

prism2pci_init: prism2_pci.o: 0.2.2 Loaded

meanwhile, lsmod shows that the module isn't actually loaded:

I know that it's not an improperly built set of modules, given that the freshly
built p80211 module loads like a charm (in fact, I get unresolved symbol errors
if I try to unload it and then load the prism2_pci module, as expected).
However, some sort of hardware weirdness does seem likely, given the output of
lspci -vv for the card:

After seeing all of this, I looked in the list archives, and to my great
surprise, I saw indications that this card isn't *actually* supported by
Linux-Wlan, but that I'd instead need to use drivers from
http://sourceforge.net/projects/madwifi/. Unfortunately, I've downloaded several
versions of those drivers, and I haven't even been able to get them to compile.

All that said, does anyone on this list know if my card is actually supported by
Linux-Wlan, and if so, what I'd need to do to get it up and running?
Alternately, does anyone have enough experience with these alternate drivers tha
they could help with them? Frankly I don't care what drivers I use, so long as
my card works. :-P

Thanks,
Alex Kirk
