Updated from the customer.
==========
Latest test using RHEL 5.4 with no modified rpm's  
kernel-2.6.18.164.2.1.el5
device-mapper-multipath-0.4.7-30.el5_4.2
kpartx-0.4.7-30.el5_4.2

multipath -ll -v2 returns expected result.
dd if=/dev/zero of=/mountpoint dumps data at expected speed.

Non modified initrd causes so many errors that it slows up the boot by four and a half minutes, when compared to running modified initrd:
mkinitrd -f /boot/initrd-$(uname -r).img $(uname -r) --preload=scsi_dh_rdac
