driver not working for netgear MA111

I was working with on my slackware 9.1 system and noticed that driver
0.2.3 came out with support for kernel 2.6.14, so I compiled a vanilla
kernel 2.6.14.3 and built wlan-ng against it. Success!

However, since I didn't need to run some legacy software anymore, I
really wanted to upgrade my aging system to the latest slack 10.2. 
After the upgrade, I tried out the same scenario that worked from
above, and this time it didn't work.  Here's the relevant output from
my system log.

prism2usb_init: prism2_usb.o: 0.2.3 Loaded
prism2usb_init: dev_info is: prism2_usb
usbcore: registered new driver prism2_usb
