boot 2.4.x *after* using 2.6.2 ???

[Michael D Schleif <mds@helices.org>]

OK, I am finally testing v2.6.x kernels on one box.

Prior to yesterdays 2.6.2 install, I had successfully used the
following:

   2.4.23-1-686
   2.4.24-1-686

This box uses lilo, and I successfully switched between these kernels at
boot time.

Then, I installed this:

   2.6.2-1-686

Yes, it booted the first time, and after I got around to loading the
following, even X and KDE work:

   mousedev
   psmouse

Nevertheless, now I cannot boot any 2.4.x kernels ;<

   . . .
   Freeing initrd memory: 5292k freed
   [ request_module[block-major-8]: Root fs not mounted ]
   VFS: Cannot open root device "801" or 08:01
   Please append a correct "root=" boot option
   Kernel panic: VFS: unable to mount root fs on 08:01

NOTE: That second line only occurs sometimes, and I cannot find any
`block' references in /etc/modules.conf -- hence the `[]'.

I have tried various lilo.conf configurations; but, here are the
current:

What am I missing?
