Bug Description

Binary package hint: linux-backports-modules-2.6.24-20-generic

Here is what goes wrong.
I have linux-backports-modules-2.6.24-20-generic from hardy-proposed installed.

sudo modprobe -v rt73usb
insmod /lib/modules/2.6.24-20-generic/updates/compat-wireless-2.6/drivers/net/wireless/rt2x00/rt2x00lib.ko
WARNING: Error inserting rt2x00lib (/lib/modules/2.6.24-20-generic/updates/compat-wireless-2.6/drivers/net/wireless/rt2x00/rt2x00lib.ko): Unknown symbol in module, or unknown parameter (see dmesg)

dmesg says:
[87359.495054] rt2x00lib: Unknown symbol rfkill_force_state

dlocate rfkill.ko
linux-image-2.6.24-20-generic: /lib/modules/2.6.24-20-generic/kernel/net/rfkill/rfkill.ko

linux-image-2.6.24-20-generic: /lib/modules/2.6.24-20-generic/kernel/drivers/net/wireless/rt2x00/rt2x00lib.ko

It appears that linux-backport-modules should ship a version of rfkill that matches rt2x00lib.
Meanwhile I'll uninstall linux-backports-modules-2.6.24-20-generic to see how the non-backported wifi driver fares.

Here is a list of all missing symbols; this should be checked in the package build process.
