Is it any better in RHEL 5.6?  
Were you able to tell if the lvm commands in the %pre script actually worked?  Try them manually from a kickstart shell; that may give a clue where things are going wrong.  If the volgroup is being created, maybe kickstart in RHEL 5.5 isn't re-reading the disk information.  Maybe there's some way to get it to do that, or at worst get your %pre script to detect whether the disk has volgroup information.  If not, create it and reboot; else write /tmp/custom-part to create the logical volumes and continue the install.
