<0>Kernel panic:  Attempted to kill init!

Possibly relevant information:

I am currently attempting to switch from using the vesafb to rivafb.
I have a nVidia Corporation GeForce 256 DDR (rev 10).
My lilo.conf append= line includes "video=riva".  The console seems to have 
successfully switched to using the rivafb driver before the OOPS occurs.
