Looks like a good plan. At the moment my available time
only leaves me to integrate things and test but no code
to this area...

says the gma500/600 is an sgx535, i.e. another variant...
There is also gma3600/3650 using sgx545. This seems to be
found in some Atom processors.
But I remember there are macros and errata in the DDK which
also cover sgx520,sgx535,sgx545 and more.
And, we have a subdirectory for hardware integration of some
Intel chips (poulsbo & cedarview) in
There is also sgx_pc_i686_tc3 where I wasn't able to find out
what it is.
