What happens if you use the device names returned by running:

   lvm lvdisplay -c

I find that those work ok in a kickstart %pre (which is close to the 
'rescue' environment) though obviously in real-life they are just symlinks 
into /dev/mapper/

Remember that the install setup has a busybox version of many apps so that 
mount may not like some option...
