Yes it does (tested at 10Mbps, since it's all what I need), at least it seems, 
for the first megabyte or so, then it receives 1K every 4 or 5 seconds. No 
errors are reported (at least I couldn't see any with ifconfig, /proc/dev/net 
and /var/log/messages).

Any suggestion on which parameters to tweak (I already tried with RX_DMA_BURST 
 1 and, in a desperate attempt, with 6)?
Never mind, I'll get an ISA card (if I can find it) and keep this one for the 
next pc.
Thank you again.
