Hi Chris,
OFED-1.5 supports ib_iser on kernel 2.6.30 only.
So, after OFED-1.5 installation you have an updated IB kernel modules 
under /lib/modules/2.6.18-164.el5xen/update/kernel/drivers/infiniband/
except ib_iser (which is coming with RHEL installation).
This prevents you from loading ib_iser module.

So, if you want to use ib_iser you should uninstall OFED-1.5 and install 
IB packages coming with RHEL.

Regards,
Vladimir
