Eric: I don't believe you've done anything wrong. I just brought up a clean 32-bit Precise install on a virtual host. I ran through the instructions* on the wiki (http://wiki.linuxcnc.org/cgi-bin/wiki.pl?LinuxCNC_On_Ubuntu_Precise). The new kernel entries got thrown into a newly created "Previous Linux versions" page of the grub menu. As you said before, unless something else is done (e.g., edit /etc/default/grub) the system boots into the default Precise kernel. Manually intervening with grub to select the kernel from the secondary page works---the system booted into the RTAI kernel, hence my first statement.
