OK, I'll risk displaying my ignorance.  Why is the old EVMS block major 117
aliased to the device-mapper module?

I don't understand what you are saying is wrong.  Are you saying it's wrong
for EVMS to check for an EVMS 1.2.x kernel?  If so, it's not true.  EVMS 2
must check for an EVMS 1 kernel.  EVMS 2 cannot run with an EVMS 1 kernel.
It can't coordinate the EVMS 2 device-mapper implementation with the EVMS 1
kernel implementation.
