I bumped into this exact same issue just yesterday. It seems to be
grsec preventing access to /sys (by modifying the default permissions).
And apparently the new i915 module wants to open stuff there. Not sure
if we should patch grsec, the driver, or somehow adjust the /sys
permissions. Should probably ask from grsec people what to do.
