gateway disappears on reboot

[Paul Cartwright <ale@pcartwright.com>]

I'm not sure what file I need to mess with . Now when I 
reboot, /etc/resolv.conf is empty, and my default route doesn't work, so I 
manually add:
nameserver 208.67.222.222
nameserver 208.67.220.220
nameserver 192.168.1.254
 

to resolv.conf & ifdown/up eth0 to get my network connection back.

What am I doing wrong & what do I need to do to fix this permanently?
did I miss an update that changed this process, or is it something in the 
interfaces file I left out..
