Unless I misunderstand you, after you issue "lilo" to write to the MBR,
then issue:
lilo -R experimental

where experimental is the name of the kernel image you want to boot. The R
creates a one time command which it will use the next time you boot, then
it will be erased.

And give the kernel an append statement:
append="panic=10"

so that if the kernel does not boot, you get automatically rebooted back
into the good kernel.
