The only kernel API the intel driver supports now is GEM, so 'have_gem'
is really the same as 'have kernel support'. If you're using user mode
setting, I think you need to call this ioctl whenever changing modes to
make sure vblank counts are correct, so that any vblank-using APIs
within the X server work right.
