here are the lines in my rc.inet1.conf that I used to get wpa working for me:
Things to check:
1. your wireless card name (udev sometimes changes this.. odd, but happens)
2. your wireless card shows up on ifconfig -a
3. nothing marked 'yes' in "rfkill list"
if all that checks out, put up your card info, my old broadcom had to use an odd config. (oh, and get rc.wireless back to stock, it's just going to hose you I think if you put a bunch of updates in it)
