The faq contains some informations about checksums: 
http://www.tex.ac.uk/cgi-bin/texfaq2html?label=checksum. Mainly it
should assure that tfm + pk and tfm + vf have the same version.

Assuming that the luaotfload code (probably the one added to the
find_vf callback) is ok and doesn't break the vf I would say the
main problem is that if with luaotfload you get a lot of harmless
checksum-mismatches you will no longer be able to see the harmful
one (when tfm/vf really differ).  I don't think that is an important
problem as tfm/vf are not much used with luatex. 

Does one get the same message with context or is the problem solved
