I think it won't work, as the /dev/sdb is not present in 'old system'.

You right ;)
But the problem is that it work in both direction. I've already tried
in the to add "root=/dev/sdb1" in 'old system' and lilo complained
that /dev/sdb1 didn't exist. Of course I could create a symlink or
change some udev rules, but the boot time of the machine does not
encourage to much 'blind tests'.

 I'll try chrooting with parameter from CD as suggested in other post.
