That makes a lot of sense, and having now done a bit of googling for 'lilo 
initrd' I've found other guidance suggesting that this is exactly what I need 
to do - copy the vmlinuz and initrd.gz across to /dev/hda1 (changing the 
names to avoid overwriting, of course!)   In fact, vmlinuz on the Ultima 
installation is a link to another file there - so I need to copy the actual 
file, not the link.

Both systems are installed on ext2 - if the first option above doesn't work 
I'll check this one, though I'd assume that if either can cope with ext2 then 
one coping with the other being on ext2 should be reasonably expected 

I'll report back after this reboot - unless Something Nasty happens!
