By the way, I too am seeing this issue -- or a similar one. I'm using an ACX111-based wireless card (a Netgear card, identified by `lspci` as "Texas Instruments ACX 111 54Mbps Wireless Interface"). I am not seeing any messages like "Driver using old /proc/net/wireless support, please fix driver !" in my syslog, however, I am seeing lots of lines like "acx: BUG: no free txdesc left". I am able to see wireless access points through network-manager, but I was not able to connect (using network-manager) to my WEP-encrypted access point. I could do more extensive testing if it'd be helpful (for instance, trying to connect via the command-line wireless tools).
