After resuming from a hibernate to disk network packets are no longer sent
and NetworkManager shows that there is no signal. Doing ifconfig wlan1
down && ifconfig wlan1 up results in the error message "SIOCSIFFLAGS: No
such device" being printed.

Is this a regression or did it work before?

Um... It is a regression and it worked before? It worked in 2.6.25 but
was broken in linux-next-20081513 .

It's not a regression. It turns out I was wrong in my other comment - this
never worked. Userspace was working around the problem by unloading the
driver before hibernation and loading it back in on resume (I switched to
module free kernel a few days ago). Building a kernel that prevents module
unloading shows similar results all the way back to 2.6.25 (although the
error switches to "SIOCSIFFLAGS: No buffer space available".
