Comment(by dsd):
Here is a kernel as requested. Set up a USB key as follows:
* boot/bzImage from http://dev.laptop.org/~dsd/20111010/bzImage
* boot/olpc.fth from http://dev.laptop.org/~dsd/20110221/olpc.fth.xo15
* boot/irfs.img from http://dev.laptop.org/~dsd/20110221/irfs.img
This sends EC command 0x32 late before going into suspend, and 0x34 during
early resume.
These commands appear to be having some effect already - this kernel
enables input wakeups by default, but the system doesn't wake up with
keyboard/mouse input. I double checked that building without my
modifications (http://dev.laptop.org/~dsd/20111010/sci-inhibit.patch)
allows the system to wake up as normal.
