multi-LUN is a module (eg runtime) option, no need to rebuild your
kernel for that at all!
from the relnotes:
- When using RAID storage configured with Logical Unit Numbers (LUNs)
greater than zero, it is necessary to enable LUN support by adding
the following entry to the /etc/modules.conf file:
options scsi_mod max_scsi_luns=255
After modifying modules.conf, it is necessary to rebuild the initial
ramdisk using `mkinitrd`. Refer to The Official Red Hat Linux
Customization Guide for more information about creating the ramdisk
image with mkinitrd.

you can 't really run kernels without NPTL on RHEL3. RHEL3 assumes the
kernel has NPTL (which allowed a bunch optimizations on our side since
apps don 't need to work with both threading libs and no longer need to
work around linuxthread bugs etc etc)

yes... NPTL.
