help.search("factanal") should get you there in a jiffy...

They're back-compatible (for a while yet) -- library(mva) will get you
the stats package, so just including the packages that were relevant
for 1.8.x should do. There are a few cases where you'll include too
much, e.g. som things were moved from MASS into stats, so these days
you might not require MASS where you did before, but that is a
relatively rare situation.
