since OPTIONS_DEFINE and OPTIONS_DEFAULT are not for the same architecture, the intel driver is never installed.
Some ports are likely to have the same OPTIONS_DEFINE/OPTIONS_DEFAULT architecture mismatch issue. I'm not sure how to fix it since the x86_64 lines are generated automatically.
x11-drivers/xorg-drivers/Makefile contains these lines:
OPTIONS_DEFAULT_i386= INTEL OPENCHROME
OPTIONS_DEFINE_x86_64:= ${OPTIONS_DEFINE_i386} OPTIONS_DEFAULT_amd64:= ${OPTIONS_DEFAULT_i386}
