I'm on the same situation. My Dell Latitude C840 with Prism54 Wifi
card is sometimes unable to restart correctly the driver. rmmod and
modprobe aren't my friends :(
On resume, I have following messages on kern.log:

Then, no more wifi... Only reboot is helpfull :(
I suppose it's a wifi card power management problem, but I don't know
how to resolve this problem.

I'm using whereami and ifplugd for suspend/resume and location
detection... It works fine for me... when prism54 is running ;)
