Hmm. One wishes one had broken the root mirror prior to doing this.

The system drops into 'single user mode' running the new kernel; it looks like its unable to see LVM2 on the appropriate mirrored disks, so fails to mount the (non critical) logical volumes. 'X' also fails to start; I suspect this is a problem with proprietary drivers. Edited /boot/grub/menu.lst and put the old kernel back to the top.
