This step may cause you trouble.  Unless you used paths like
/mnt/newslash/vmlinuz in /mnt/newslash/etc/lilo.conf then
lilo will be pointing to your old kernel/other files; this
shouldn't be a problem the first time you boot, but you'll need
to run lilo again to get things sorted and stable.

While many BIOS/SCSI combinations play nicely together, many
combinations also have real and sometimes intractable issues
over booting.  In your position I'd probably make a boot floppy,
just in case.
