0.17, but some more testing showed that the ns83820 actually works
just fine during this test when using just crossover cables and
running at gigabit speed. The original testing was done using
100Mbit hubs, so my guess would be that the 83820 chips (and/or
driver) doesn't handle collisions too well (which I don't have a
problem with, as afaik GE is always switched).

However the DFE-580TX problems remain regardless of using a hubbed
or switched network.

(As booth eepro100 and tulip-based cards works fine with the hubs
I'm quite certain there's nothing wrong with them.)
