Here's the fix to get the 3C509's to reset after warm boots.
It's relative to the 2.0R source base.

There's most definitally a reboot problem. It existed in 1.1.5.1 and it's
still in Andres's code. I did fix it in the the old driver but I haven't
got to fixing it in the 2.0R release. I brought home a second 509 to
check out how well the multi-card support works as well.
I thought I look at the 509B problem that was reported but 3COM hasn't
posted any addendum to the tech ref yet and I don't have one.
I can tell you that the reboot problem used to be due to not soft resetting
the card correctly in epprobe. I got it right by trial adn error the last time.
