[ltp] No eth0 on T520, Ubuntu 10.4 LTS

[Steven J. Owens]

Hi folks,

     I need to use my t520's wired network (to configure a new
router/AP) but I'm not seeing eth0 show up at _all_.  I've tried
everything I can think of i

     If I plug a cat5 cable in, I get green lights on both ends.

     ifconfig -a only shows lo and wlan0.

     lspci didn't show an ethernet controller lsmod didn't show any
likely drivers, some googling suggested module e1000e. 

     http://ubuntuforums.org/showthread.php?p=11295928 

     Did "modprobe e1000e" and now it shows up in lspci, here's the
"lspci -v" output:

     But still no eth0:

     On the unlikely chance, I checked BIOS, wired ethernet is still
enabled in BIOS.

     Any clues?
