Intel Corporation 82573L Gigabit Ethernet Controller not recognized / in list of ethernet controllers

Answering to my own question... I was not connected to the internet during the installation procedure as I normally connect to the internet via an USB modem ("emobile" modem, which is equal to Huawei E220, see http://en.wikipedia.org/wiki/Huawei_E220 ). This caused the installation procedure to present me with the following screen: No Ethernet card was detected, but a FireWire interface is present. It's possible, though unlikely, that with the right FireWire hardware connected to it, this could be your primary Ethernet interface. Do you intend to use FireWire Ethernet? [yes] [no] I choosed [no] and got a list of ethernet drivers to choose from. Searching the internet I found that the right choise In my case (IBM x60s laptop) seems to be e1000: Intel (R) PRO/1000 Gigabit Ethernet. But selecting this one I got the same screen again: No Ethernet card was detected[...] Finally I choosed [yes] as answer to Do you intend to use FireWire Ethernet? and could install the system. I suppose that the option No ethernet card from the list of ethernet drivers would have had the same result. After some trial and error I could use my USB modem and connect to the internet as I could before when using Debian. Yesterday I had the opportunity to use an ADSL connection which also worked immediately without installing any new driver. So the ethernet card detection mechanism seems to rely on a working internet connection and not on the hardware by itself - which I didn't know -. When not connected to the internet during the installation procedure the option No ethernet card (or mayby Do you intend to use FireWire Ethernet? -> [yes]) seems to be the right way to go...
