I played with it for a couple hours and my experience was:
- It created the multipath configuration, though in %pre I had to
run multipath to enable multipathing support
- It could then see the device but would not install to it, after
creating a partition in my experience multipathing has to be
restarted, so the only way I think to get it to work is to come
up with a way to manually partition in %pre and then tell kickstart
to use the pre-existing partitions after restarting multipathing
in %pre. Quite a bit more work than I expected given the few notes
I have seen saying that it should "work". Given my timetable I
decided to give up on this for now and use internal disks, I can
re-visit it again later.
VMWare ESX 3.5 works flawlessly when booting from SAN by contrast!

thanks for the info!
