Here is my complete route table:
 ./route
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use 
Iface
69.13.211.0     *               255.255.255.192 U     0      0        0 eth0
169.254.0.0     *               255.255.0.0     U     0      0        0 eth0
default         69.13.211.1     0.0.0.0         UG    0      0        0 eth0

The big difference between mine and yours is that the 169.254.0.0 route 
is showing up on eth0 - which is the only port connected. I can get into 
the box, but the box can not get out to anyplace. I could be looking in 
the wrong place for the solution, I figured that this looks wrong to 
have this apparent self-assigned IP on my only active ethernet port.

This is my only active port. If I shut it down, the machine goes away.
