Can I do a one-time boot to non-default kernel in Lilo?

Unless I misunderstand you, after you issue "lilo" to write to the MBR,
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:
so that if the kernel does not boot, you get automatically rebooted back
into the good kernel.
