Connecting to Comcast

Hi All,
I've *finally* got a cable modem (after waiting about 7 years:) 
however, I can't seem to get Linux to connect.

I've tried getting a dhcp address from the modem, but nothing happens.
The "PC/Activity" light is flashing an awful lot, but it seems to do 
this even when the interface is down (I'm assuming this is lowlevel 
link-layer traffic).

I've tried using pump to get an address, and watched daemon.log and 
an ethereal trace, and both show a bootp request going out, but 
nothing ever comes back.

Does Comcast require you to register MAC addresses?  I know MediaOne 
did, but the guy came today and just hooked up the cable modem and 
left.  I just got basic installtion, so he didn't muck with the system
at all in order to get a MAC address from it, nor did he mention to 
my wife that I'd have to do this.

Anyone have any ideas?  So far I've if[up|down]ed the interface 
(eth1, netgear), I've power-cycled the cable mode, etc.
No firewall script yet, so that's not causing any problems.

  Kernel 2.4.19 (yeah, I need to upgrade)
  Debian sid
  Comcast
  Motorola Surfboard SB5100
  Netgear NIC

Any info would be great, thanks!

	It may look like I'm just sitting here doing nothing,
   but I'm really actively waiting for all my problems to go away.

	 If you're not having fun, you're not doing it right!
