This should now be fixed on the trunk (well, the FSF server are very
slow today, so I'm having trouble pushing anything), but...  that
cmuscheme.el file is rather odd: It doesn't create a new mode or
anything, but just alters the scheme.el mode things, which means that
after you've loaded it, you can't use the regular scheme.el mode any
more.

Which is a very unusual way of doing things, to put it mildly.
