Need to install on LUN past 8

[isplist at logicore.net]

I've tried everything I can find and think of or that has been suggested.

I have a Xyratex/MTI type chassis split into 32 volumes. I need to install 32
blades onto each volume so that I can remove the drives on each blade.

When I start a Linux install on a blade, it never sees all of the volumes, 
only LUNS 0/1. I need to see all 32 LUNS so that I can install all of my 
servers.

I've tried all of the following;

RHEL4, CentOS4.4, others. I don't really care what the distro is, so long as 
it runs basic services such as web/php, qmail, etc. What I do need however is
that they be GFS/Cluster machines.

I've tried passing the information at the installers command line;

scsi_mod.max_luns=256
scsi_mod.scsi_dev_flags=INLINE:TF200:0x242

I've tried many variations of these types of commands with no result.

I've then set up a PXE boot server thinking that I might be able to pass the 
options using pxelinux.cfg. Still no luck, it only sees two LUNS.

I've tried installing from network with a recompilled initrd.img from a 
machine which was already installed and modprobe.conf modified to see the 
LUNS. The donor server can see all of the volumes, the installing version dies 
with a kernel problem since it cannot see the same already installed volume.

What in the world can I do? Is there a guru here who can tell me how I can do
this?

Thank you VERY much for reading this :).
