As Michel pointed out:
There will [always] be compelling reasons why users/distros prefer
xf86-video-foo over the modesetting one.
So, barring time concerns, updating those is good idea, imho.

Pretty we don't want another DRIVER_KMS_LEGACY_CONTEXT, because user X
decided to stay with the final version of xf86-video-foo which still
uses nasty libdrm/ioctl Y ;-)
