For anyone who has the en2 or whatever problem for their ethernet card.  TM needs en0 to work properly.

Very simple instructions on the Apple support site.

Worked like a charm for me.  At the bottom of the page...


Red "i" message: "Time Machine could not be configured. The built-in network interface could not be found"

From the Finder's Go menu go to this location:
/Library/Preferences/SystemConfiguration/

Copy the file "NetworkInterfaces.plist" to the desktop (to make a precautionary backup).
Delete the file "NetworkInterfaces.plist".  Enter administrator name and password if prompted.
Restart your Mac.  
Once restarted, reconfigure your the Network and Time Machine preference panes in System Preferences.


Once I did this, I opened the network preference, deleted my old network connection and created a new one...automatically named en0!  

Enjoy

If you did this:

got IONetworkingFamily.kext from 1st page and placed it in /System/Library/Extensions

sudo -s

rm -rf /System/Library/Extensions.mkext
chmod -R 755 /System/Library/Extensions/IONetworkingFamily.kext
chown -R root:wheel /System/Library/Extensions/IONetworkingFamily.kext

and there is no result, try this:
get your IONetworkingFamily.kext back and restore network settings.
Your Ethernet should be renamed automatically as en0 after you moved old NetworkInterfaces.plist into Trash and restart your PC.
If your en0 Ethernet is working well you can fix your Time Machine:

download EFIStudio
run it and add device Ethernet

then write it in the com.apple.Boot.plist (there is the button)

reboot and enjoy

I resolved this problem of failed backups by updating to 10.5.8 thru software update and reinstalling cameleon bootloader...
