This requires support at the hardware level. (You can't have CPU code running to decode IR pulses when your CPU is "asleep".) I know of two video chips supported under linux that provide such a function. Wake-up from IR for these chips will rely on the kernel PCIe or USB infrastructure supporting PCIe or USB Power Managment Events from hardware. It will take a huge amount of work and time to get the respective linux video drivers to properly support suspend/resume properly. If you're waiting for me to get that working, I'll advise you to plan on getting off the couch and pushing the power switch for some time to come. ;) The MCE-USB, I *speculate*, can perform wakes. It's driver would need to support that, if it can.
