Starting gnome after text-based install

["Robert Moskowitz" <rgm htt-consult com>]

I have just dropped Centos 5 on a laptop with only 256M  memory.  
Problem was 24M is shared with the video card so the installer insisted 
on text, not graphical install.

I DID install gnome and specified it as my interface.  But when I do an 
init 5, I come up in X not Gnome.

What do I have to change to fix this aberrant behaviour?

Oh, for those not familiar with Centos 5, it is basically RedHat 
Enterprise 5 which is based on FC6.  Or so I am told anyway!
