The Geode GX + CS5536 combination is new to me, but it also means you
should be able to reuse a lot more of the v3 code (no CS5535 support
Actually, I'm pretty sure it will be even easier to modify the v3 code
to support your board because you only have to modify the LX code to
support GX and you can skip CS5535 support.

However, there are some targets in v2 which have the GX/CS5536
combination (AMD Rumba, OLPC rev_a+btest), so using v2 is also
definitely an option. Please be aware that support for the OLPC
mainboards may have bitrotted (and it had special OLPC-only code).
