i965 doesn't support MS images because on Gen7-8 it would involve either
converting all MS textures to UMS on the fly or implementing the
compressed MS layout in software, which would be even more madness.  On
Gen9 and up though it's supported natively by the hardware and it
shouldn't be too difficult to implement, I just haven't had the chance
to do the work yet.
