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 ;-).

Can we start to get some debug logs about what happens when you try to
ping (and it fails)? Please ensure driver is compiled with debugging
(CONFIG_IWL3945_DEBUG) and load the module with debug=0x43fff
Also, please submit a bug for this
( http://www.intellinuxwireless.org/bugzilla/ )to help us keep track of
all the debugging output you are providing.
Thank you
Reinette
