I have read the reason behind the desertion of the page is because Glamor is merged together with xorg-server and so there is no need of a separate Glamor page and codebase.

I used the following in a file in xorgconf.d/ on one of my boxes
which ran a low-end radeon variant where glamor improved the power
consumption (Aruba, if my memory is correct - the motherboard seems
to have died).  You'll need to change at least the Driver.

# turn glamor on
Section "Device"
	Identifier "radeon"
	Driver "ati"
	Option "AccelMethod" "glamor"
EndSection

But I think you may be missing a dependency - the version of glamor
in xorg-server-1.17 uses libepoxy, and the only reference to a
glamor lib in my logs is for libglamoregl.so in the xorg-server's
modules.

Alternatively, if by 'configure' you meant "which options do I pass
to ./configure" the answer is '--enable-glamor'.
