You could be having a problem with your nic at 100baseTX when your 
isp is at 10BaseT, but it sounds like your kernel sets that up right
initially, but it would be worth looking into if the module gets
unloaded and reloaded wrong.

However, your comment regarding pump says that it is not 'kernel code'
but in fact pump.  You saying it never hears anything back is 
definitely suggestive that the packets are being blocked.  What 
happens if you bring down your firewall and let all packets in, then
run /etc/init.d/networking restart?  You may have said you did this,
already, but I wasn't sure based on your email.

If the above works, you need to adjust your firewall rules.  If it does
not, then I suggest trying dhcp-client or dhcpcd.  The former is from
ISC, and is what I personally use.  In the past, I had problems using
pump whenever I tried to restart it, but my understanding is pump
works better now-- like I said though, I use dhcp-client now.

If you get it to work, but can't get the firewall rules right, I
would be happy to help with that if you want to send me your 
/var/log/syslog file that has the DROPed packets logged.  I don't
need the whole thing, so just grep out the firewall stuff and send
me that.
