Sadly, no.  But I am using a LP9002 happily on RHEL3.  It does work just
fine, with a few gotchas.

Note that, when you build the module using the driver source, it by
default looks at the Makefile in /usr/src/linux.  On RHEL-3 the
EXTRAVERSION variable is set to have "-custom" in it.  Thus when you do
"make install" in the driver source tree it gets installed into 
"/lib/modules/`uname -r`-custom"  which insmod will fail to use because
it's in the wrong module path.  I normally just make the module, and then
hand copy lpfcdd into the right place.

Also note that since lpfcdd isn't in RHEL kernels, kernel upgrades on
boxes with the driver in /etc/modules.conf will break because the %post
scriptlet in the kernel rpm's try to remake the initrd and fail because the
module isn't findable.  You'll need to manually make, copy and remake the
initrd and edit your bootloader config (typically /etc/gub.conf) with the
correct info.

You can skip this step by not having lpfcdd in /etc/modules.conf ot the
disks on the SAN in /etc/fstab and simply writing a init script that loads
the module(s) you need and then brings the disks online (either though a
mount or by doing a vgscan -a, etc.. if you're using LVM)

HTH,
