One of the 'gothchas' with the RHEL distros is the
supported/unsupported kernels RPMs. The 'stock' (supported) kernels
are 'missing' a pile of drivers (the ones that *RedHat* does not
support). I suspect that the driver the OP needs is in this set.
There is a 'chicken and egg' issue here. For devices that are not
needed during the install (like a sound card or the like), you'd just
*manually* install the kernel-<mumble>-unsupported-<mumble>.rpm as part
of your 'post install' process. I did this for sound cards and for
FireWire (the IEEE1394 modules are considered 'unsupported') on several
different machines I installed WBL 3.0 on (WBL 3.0 == RHEL 3.0). If
these drivers are needed to install (typically the driver for the SCSI
RAID controller) it is lots more fun. You need to create an
alternative boot-install disk that has the 'missing' modules or a
driver disk. The modules are on the install disks, locked away in the
"kernel-<mumble>-unsupported-<mumble>.rpm" (which I think is on disk
3). One option would be to get some random other PC with more 'vanila'
hardware and install RHEL on this machine (or WBL/CENTOS, which are the
same, in case you are paranoid of RH). Then you install the
corresponding kernel-<mumble>-unsupported-<mumble>.rpm (the version
that *matches* the boot/install kernel) and copy/burn the needed
modules to floppy/cdrom and then go back to the PowerEdge box and go
from there with your 'driver disk'.
