Fine! I'll give it a try if something breaks with compile.

Ah, oh...

drivers/gpu/drm/pvrsgx/Makefile

       $(Q)SOC_VENDOR=intel SOC_FAMILY=poulsbo SOC=gma500 SGX=sgx530 SGX_FLAG=SGX535 SGX_REV=126 $(MAKE) TARGET_TYPE=$(CONFIG_SGX_POULSBO) $(build)=$(SOURCE)

should of course be SGX=sgx535

Maybe you can try and send a patch. Or I make one with "reported-by:".
