I have a similar config:
dual 350MHz P-II with 1 Intel EEPro100 onboard
kernel versions 2.0.35, 2.0.36, 2.0.128 
driver versions 1.06 and 0.99B.
Netatalk versions 1.4b2+asun2.1.0 and 1.4b2+asun2.0a18.2.

I have a similar problem. If I don't set the module option
multicast_filter_limit=0, I crash the local network here (router starts
resetting my port, I hog all the bandwidth, etc.). When I set that module
option under 2.0.35/2.0.36, when xntpd starts up, I get a Transmit timed
out and then the ethernet layer gets reset. After that, it works. My guess
is that there seems to be something still wrong with the multicast filter.
Other than that it seems to work great.
