IIRC, the ipw3945 uses a separate regulatory daemon. Have you checked if
this daemon is still running after hibernate/resume? Maybe the suspend
scripts you are using are stopping this daemon. Btw, which one do you
use, acpi-support, hibernate or powersaved? Check the file
/usr/lib/hal/scripts/linux/hal-system-power-hibernate-linux (You can
also run it manually as root).
I doubt it's a bug in NM, rather in the driver.

Cheers,
Michael
