thanks for providing the package for OS2006, that is great news. I installed 
it and it did not break anything as far as I can tell. The only thing I am 
surprised is that the module is reported as cx3110x  by lsmod:

Nokia770-49:~# lsmod
Module                  Size  Used bycx3110x                51736   0
ext2                   43524   1
umac                  253316   1 cx3110x
Nokia770-49:~# dpkg -L cx3110x-hotfix-bug2006
Nokia770-49:~# cat /etc/init.d/cx3110x-hotfix-bug2006
# startup script for memory corruption bugfix
# unload cx3110x module and load fixed one
# see bug "Memory corruption during WLAN use" - 


case "$1" in
        module_name=/lib/modules/`uname -r`/cx3110x-hotfix-bug2006.ko
        if [ -f $module_name ] ; then
                rmmod cx3110x
                insmod $module_name
                chroot /mnt/initfs wlan-cal
                echo "fixed cx3110x module loaded"
                echo "$module_name not found, nothing done"
        echo "Usage: $0 {start|stop|restart|reload|force-reload}"
        exit 1

exit 0
Nokia770-49:~# ls -l /lib/modules/`uname -r`/cx3110x-hotfix-bug2006.ko
-rw-r--r--    1 root     root        63220 Nov 16

dmesg seems to tell that the fixed driver is loaded:

[    6.173858] CX3110x chip variant: STLC4370
[    6.293853] CX3110x: firmware version:
[    6.294067] Loaded CX3110x driver, version 0.8
[   14.495483] Unloaded CX3110x  driver, version 0.8
[   14.611755] CX3110x chip variant: STLC4370

[   14.777069] Loaded CX3110x driver, version 0.8.1-bug2006-fix1

Again, many thanks for providing the package.
