Is there documentation of /sys/module/iwl3945/drivers/pci:iwl3945/{un,}bind somewhere? I believe that's the next step, but could not figure it out.
After reboot, network will work (I believe ;-). Pavel -- (english) http://www.livejournal.com/~pavelmachek (cesky, pictures) http://atrey.karlin.mff.cuni.cz/~pavel/picture/horses/blog.html
