Yep.  This is a known issue with an upgrade from 4.X to 5.X.  The new
boot loader will look correctly in /boot/kernel/kernel for the 5.X
kernel, but the first time you're booting with the old 4.X loader, and
you have to interrupt it, unload the old kernel and load the kernel from
its new location at /boot/kernel/kernel instead.

This should allow you to boot single user with the 5.X kernel and then
move on to installworld as usual.
