Strange, we haven't had any hassles with that here:
csae:/home/g89r4222#ping -f -c 2000 cspp2 ## Linux box 486DX33/SMC Elite
PING cspp2.ru.ac.za (146.231.129.181): 56 data bytes
.......
--- cspp2.ru.ac.za ping statistics ---
2006 packets transmitted, 2000 packets received, 0% packet loss
round-trip min/avg/max = 2.686/7.013/89.561 ms
Braae:/home/g89r4222#ping -f -c 2000 csmsc1 ## FreeBSD box 486DX33/SMC Elite
PING csmsc1 (146.231.129.40): 56 data bytes

I wouldn't think you could say either has problems with packet loss,
given the above flood-ping output. (The Linux Box seems perhaps marginally
slower.)

Interesting, there have been cases we've had of a Linux box losing its
(FreeBSD) NFS server, but we ascribed that to network problems (I'm not
convinced that our problem was Linux's fault).

This is a more likely cause of your packet loss -- The NE2000 is not
the fastest of ethernet cards.

In Release 1.1.5 (due RSN) the Linux FP emulator is available as an
option. Unfortunately it's not in the GENERIC kernels, due to the code
being under GPL.
