Hi this is definitely possible, we have had to do similar.

What I would suggest is that you install one system using a driver disk 
or similar so that you have a working system to use to help identify 
changes needed to your initrd.

There is a lot of good documentation about modifying initrd's its just 
that some of it needs to be adjusted slightly for newer Red Hat based 
systems.

And remember just because the initrd used for PXE Booting is modified 
doesn't mean that the initd on the installed systems is modified as 
well.  I hope this helps

Good Luck :)
