2.2.x & ne2000 compatible = big slowdown compared to 2.0.x

I have the following setup:

Server:
- 486DX2 66MHz
- kernel 2.0.36
- ISA ne2000 compatible network card

Client:
- Pentium 233 MHz
- kernel 2.2.9
- ISA ne2000 compatible network card

With this setup, any transfer between the two machines never go faster
than 12 KB/sec on FTP transfers and approx 30 KB/sec on HTTP transfers.
Linux 2.2.5 also gave the same results.

However if the client machine is reverted to Linux 2.0.36 then all
transfers go up to 200 KB/sec.

Any idea why there is so a big difference between 2.0.36 and 2.2.9?
