Ironically, I used to write hardware RAID configuration software in a 
previous life :)

In theory, it should be possible to (a) retrieve the OEM command line 
tool in %pre (wget?) and configure hardware RAID with it there (in 
%pre), so you wouldn't have to rebuild the initrd just to add the raid 
tools.  Either way, after running the RAID tool in %pre you will 
probably have to do something like scsi-add-single to get Anaconda to 
see the new drives prior to partitioning setup.   Linux does not 
generally discover new logical drives without being told to look.   Your 
driver/RAID tool might vary though.

I haven't really tried this to see if it would work, but I don't see why 
it wouldn't.

Obviously you are also going to need your drivers for the particular 
hardware installed first, so you'll probably want to look into the 
"driverdisk" option in kickstart if they
are not enabled by default.   Using the shell (Control-Alt-F2?) is 
probably a good idea to do this all manually the first time, to see what 
problems you might encounter.  Possibly put a sleep in pre to give you 
some time to test your commands within the boot environment and then 
write down what you need to do.
