Yes, the intel gallium drivers aren't well supported, but the other
gallium drivers support gbm and EGL/GLES2 just fine.  We use that
combination for Wayland.  If you're just using gbm, kms and EGL/GLES2,
it doesn't really matter whether your driver uses gallium or not, it's
really just an implementation detail.  Similar to how it doesn't
matter to X clients whether the X server uses the EXA, UXA or XAA
acceleration architecture.
