It also works here (with a Debian chroot).

I have tried to enable the NE2000 ISA card in the kernel (a small tweak is needed in a KConfig a file), but I wasn't successful. The card is not fully detected when the module is loaded, so I had to give the IRQ number by hand. Then the ethernet device is recognized, the MAC address is also recognized, but when I want to transmit data I only get timeout messages from the kernel... -- .''`.
