The problem happens because of the kernel running. I strace'd the install and got the error "FSET lvm2/kernel seen false
10 lvm2/kernel doesn\'t exist"
I've not tried it yet, but I suspect putting lvm2 on hold as the others suggest, finishing the install, then rebooting into the 2.6.15 kernel, is the way to go.
