ubr924 modem does not want to talk through its ethernet0 port

I have here one of those ubr924 cable modems and was going to configure it so I could connect it to my switch and then tftp new OS to it. I thought that would be an easy task:

o Connect the router's hub port to the switch using a crossover cable. cable-modem0 is not connected to anything for the time being.
o Using the console cable, configure the modem:

!
hostname burpmaster
!
!
clock timezone EST -5
ip subnet-zero
no ip routing
!
ip audit notify log
ip audit po max-events 100
call rsvp-sync
!
interface Ethernet0
ip address 10.0.0.7 255.255.255.0
no ip route-cache
bridge-group 59
bridge-group 59 spanning-disabled
!
interface cable-modem0
no ip route-cache
shutdown
bridge-group 59
!
ip classless
ip http server
no ip http cable-monitor
!
snmp-server enable traps tty
snmp-server manager
!
voice-port 0
input gain -2
output attenuation 0
!
voice-port 1
input gain -2
output attenuation 0
!
!
line con 0
line vty 0 4
!
scheduler max-task-time 5000
end

burpmaster#
(yes, I did not put any passwords on it just yet)

o Check if Ethernet0 seems to be properly configured:

burpmaster#show interfaces e 0
Ethernet0 is up, line protocol is up
Hardware is PQUICC Ethernet, address is 0003.6bbd.66f2 (bia 0003.6bbd.66f2)

burpmaster#


o Ping itself:

burpmaster#ping 10.0.0.7

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.0.0.7, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/4 ms
burpmaster#

So far so good, but this is when the fun begins:

burpmaster#ping 10.0.0.1 <----- Ping my Linksys router, which is being used to connect to the Motorola cable modem I am currently using.

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.0.0.1, timeout is 2 seconds:
......
Success rate is 0 percent (0/5)
burpmaster#ping 10.0.0.13 <-- Ping my unix box, which I am using to connect to the ubr924 modem's console port.

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.0.0.13, timeout is 2 seconds:
......
Success rate is 0 percent (0/5)
burpmaster#

All I can think of is a bad crossover cable, but yet I have used that same cable many times before, including to upload new images to my switch though tftp. I am willing to have it checked later on today. But, if the cable is ok, what else should I check?
