Don't you hate that? I am in South Australia and maintains systems all across Australia, so I know what you're talking about!

I noticed that the version of LILO that is included in the version of Debian version that we're using at work at the moment has a command line switch when you run it to tell it to only boot the new kernel once and then switch back to the default kernel. This reduces the problems of having to have staff on-site selecting the kernel at boot time. If it panics, we tell them to just hit the reset button and it'll come back up on the old kernel.
I went looking for that option on my redhat/fedora machine and couldn't find it ..
Fedora Core 1: [EMAIL PROTECTED] darryl]$ /sbin/lilo -V LILO version 21.4-4
Debian Woody: [EMAIL PROTECTED]:~$ /sbin/lilo -V LILO version 22.2
~From memory the option is the '-R' command line switch. (And typical, now I go look for it, it's on that Fedora machine!)

Generally the only thing that will stop a machine from booting (in my experience anyway) is missing the drivers for the hard drive controllers, the root file system or perhaps not enabling the console.
Once the system has booted far enough to mount the root filesystem then the rest of the drivers that are in /lib/modules/`uname -r` become available.
If you can't build the drivers into the kernel (or haven't) then you need to build an initrd. That's normally just a case of:
[root]# mkinitrd /boot/initrd-`uname -r`.img `uname -r`
Of course you need to tell LILO/Grub to load it, but that's generally all it takes.
HTH!
