Why don't you made a custom initrd image which would print out what
you type to be sure that you use right password. You just need to
catch password with "read" and print it out.

I have such an image somewhere and I could send/modify it if you are
not able to make it yourself. You would just need to put in your
lilo.conf or whatever boot manager you use.
