I just tested 1.3rc4 with MX and it uses the btl by default. The
reason is the cm init lowers the priority to 1 unless the MTL that
loaded is psm, in which case it stays at the higher default of 30.
It's a fairly easy fix, I think. But the last time this was discussed
people in the group had objections to using the MTL by default with MX.
