I had the same kind of problems on my Libretto 70CT and a 3Com 3CCFE574BT.
After the installation (5.1 and 4.9) over SLIP, the NIC kept giving me
extremely low throughput. I did a little testing:

Pinging from the libretto to another system, both running tcpdump, would
give normal results on the other system (1 ICMP request arriving every 
second, 1 reply being send back).
On the Libretto however, the replies would not show up in the tcpdump
trace for a long time, sometimes over 60 seconds, after which I would
see a "burst" of replies in a few seconds, but a lot of them never 
showed up at all. 
So it looks like the problem was in the receive side of the NIC/driver.

The hardware is fine btw; the Linux driver has no problems with this
configuration.
