Nope, because thats identical to /lib/firmware/iwlwifi-5000-2.ucode:
jorschiedt@trinity:~/Desktop> md5sum
iwlwifi-5000-ucode-8.24.2.12/iwlwifi*
10ca882a6e16e0d79e5f4b2b1b516e4e  iwlwifi-5000-2.ucode

jorschiedt@trinity:~/Desktop> md5sum /lib/firmware/iwlwifi-50*
4382e0ee86e57b9e5fdd1f77652da391  /lib/firmware/iwlwifi-5000-1.ucode
10ca882a6e16e0d79e5f4b2b1b516e4e  /lib/firmware/iwlwifi-5000-2.ucode

Only by switching off the 802.11n I got rid of the problem - but thats
really not my favorite solution...

jorschiedt@trinity:~/Desktop> cat /etc/modprobe.d/50-iwlagn.conf 
options iwlagn 11n_disable=1 amsdu_size_8K50=1 fw_restart50=1
11n_disable50=1

Cheers, Jürgen
