1. without any conf files:
(WW) RADEON(0): glamor requires Load "glamoregl" in Section "Module", disabling.
(WW) RADEON(0): Direct rendering disabled

and llvmpipe in glxinfo

2. with only the Load "glamoregl" in config - crash in libllvm:

Looks like this isn't #66359, since glx gets loaded after glamoregl (this wasn't the case with xorg-xserver 1.7 in xubuntu 13.04, but the crash was exactly the same)
