Knoppix "sees" the card during the autoconfiguration.
But, when it tries to load the e1000.o module it says it can't find the card. "No such device"
Perhaps there is a newer driver. Also the video doesn't detect but that is fixed in the latest CVS of XFree86.

The system is as follows:
Dell Optiplex GX260
Pentium 4 1.8Ghz
256MB DDR
Intel 845GL (Brookdale-G) with onboard video
Intel Pro/1000 MT PCID: 8086:100e
SBLive Value 5.1
ISA Riser board.
