[arch-general] is mesa, glproto, dri2proto not needed by intel video driver anymore?

Hi, If i run 'pacman -Qdt' (search for not needed installed packages) i got: dri2proto 2.8-1 glproto 1.4.16-1 mesa 9.0-1 If i remember right, these were intalled by xf86-video-intel, or intel-dri in the past. So, my question is: can i remove these packages safely? My video card is: 'Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller' and i am using intel driver, with KMS (i915).
