CPU
Intel Atom N270 supports HyperThreading, so you can set MAKEOPTS="-j3" in /etc/make.conf. Setting processor type in the kernel is bit complicated. Modern kernels (>=2.6.33) have "Intel Atom" choice, but for lower kernels you must use "Core2/newer Xeon". For GCC<4.3.4 you must set this:

For newer GCC you can set march=native, but if you want use distcc you must set CFLAGS as shown above

Video
Video configuration is fully described here. I advice you to enable KMS. Note: KMS didn`t work for me untill i compile agpgart and drm into kernel, not as modules. Probably you need to do so too.
