Right! So: let's say I can figure out what the error is (I'll see if I can get all of the error message at once, and probably post it here.)
Let's say I can go about trying to build a different kernel with the appropriate support for my SCSI devices. Where does OSCAR grab the kernel that it installs on the nodes?
I can offer you something here. OSCAR uses the kernel found in the base rpm list by default. The kernel would be the one that's rpm installed by the distro in that case. The SIS boot kernel (the one that is used for network booting and installing the nodes) is different and separate though, and can be found in /tftpboot. If you use the kernel_picker package, you have the option of selecting a different/custom kernel that you point to to replace these kernels if necessary.
The default kernel within the image can be configured with a config file... e.g.: /var/lib/systemimager/images/oscarimage/etc/systemconfig/systemconfig.conf

How should I go about modifying it? I'm at home right now, so I don't have the chunk of the manual that deals with a custom kernel. I can probably manage to build a kernel with the appropriate drivers linked in, if I just know what kernel source I'm supposed to be modifying!
Thanks for the help, and by the way, your earlier message was right on the money--I hadn't copied in the boel_binaries.tar.gz file--I got lucky enough to figure this out along the way.
