I've found a bug with the "wl" kernel module, and I'd like to report a bug. I'm not sure what package provides it, though.
Based on this thread, it seems that Broadcom directly provides the
wl module. Their code page for it is here: http://www.broadcom.com/support/802.11/linux_sta.php.
It looks like they want you to email support requests to the address provided on that page.
