OK.  Something is definitely missing here.  Notice how 
(http://www.redhat.com/magazine/024oct06/features/kickstart/) GRUB 
contains options for setting the IP address, netmask, and gateway for 
the system you intend to boot.  These arguments are /*not*/ set in 
/your/ grub configuration.  As to why they are not, either you didn't 
specify them during your cobbler system provisioning OR there is some 
kind of a bug in koan's 'reprovision' logic.  Likely the former.  Please 
double check that you specified

cobbler .... --ip=X --subnet=Y --gateway=Z ...

in your provision command.
