That can work, but if you have any hands-on support at the colo at all, 
you can probably overnight them an install CD and talk them through 
booting with 'linux vnc vncconnect=n.n.n.n' (address of your vncviewer 
in listen mode). Or maybe you can make that happen from a kickstart and 
do the rest from your desk.  I sometimes use that feature just so I 
don't have to stand by the bench where I'm setting up a new server.
