Everything you need is in the kernel:
http://dev.laptop.org/git?p=olpc-2.6;a=tree;h=stable;hb=stable

For suspend to RAM and SCI handling (the most interesting part so far),
the file you want is

http://dev.laptop.org/git?p=olpc-2.6;a=blob;f=arch/i386/kernel/olpc-pm.c;h=0ba72bab014bcc63d4ae52a560cb717f9bcbf434;hb=stable

You'll also want to investigate OHM, which is the userspace power controller.

Good luck.
