Can you double check rfkill module is from compat-wireless
and not from you kernel?
Or maybe compat-wireless is currently broken, try an older tarball.
It doesn't look at first glance like a rt2x00 specific issue.

BTW, output from dmesg also contains the actual crash
reason which is not in /var/log/messages due to your syslog config.
