Weird behaviour on iwl3945 module

[Rafael Cunha de Almeida]

Hello,

I'm using Debian lenny (linux 2.6.26) and I have a iwl3945 wireless
card. My laptop is a lenovo r61i. I've notice that, when I turn off
the wireles/bluetooth switch the wireless module isn't removed, the
kernel even displays a few warnings:

% dmesg | tail -n11
[ 1219.735652] iwl3945: Radio Frequency Kill Switch is On:
[ 1219.735652] Kill switch must be turned off for wireless networking to work.
[ 1219.787767] usb 1-1: USB disconnect, address 2
[ 1221.291865] iwl3945: WARNING: Requesting MAC access during RFKILL wakes up NIC
[ 1221.294246] iwl3945: MAC is in deep sleep!
[ 1221.341983] iwl3945: WARNING: Requesting MAC access during RFKILL wakes up NIC
[ 1221.345953] iwl3945: MAC is in deep sleep!
[ 1221.405968] iwl3945: WARNING: Requesting MAC access during RFKILL wakes up NIC
[ 1221.450835] iwl3945: MAC is in deep sleep!
[ 1221.612230] iwl3945: WARNING: Requesting MAC access during RFKILL wakes up NIC
[ 1221.632612] ACPI: PCI interrupt for device 0000:03:00.0 disabled

So, when I turn the switch back on, my wireless card is not
operational. I have to manually remove and then reinstall the iwl3945
module in order to the device to resume working. The bluetooth device
doesn't have that issue.

Is that an expected behaviour? Would it be impossible or undesirable
to the kernel to behave differently? Is it already fixed in the newest
kernel version (or on the -mm branch)? I am willing to hack into the
kernel code in order to fix that problem, if someone would give me
pointers of where to start.
