So, the DRI option has absolutely nothing to do with kbd/mouse.  I
expect that what you are actually seeing is a hard lockup, quite
possibly a gpu crash.  At the moment, the drm support in 7 and 8 should
be in sync, but 9-CURRENT has 3d bits for radeon r600+ cards.
Additionally, libdrm and dri enable/disable certain code paths based on
kernel headers found at build time.  It is quite possible that these are
not entirely compatible with the compat libs right now.

I would expect the damage to be constrained to one or both of the above
ports though.
