Sorry for confusing you. I thought that was the one, but the wakeup via
a remote control is described here

Yes, I meant a USB IR Receiver and I meant to connect it to a USB port.
Then you put these lines in your /etc/rc.local before the exit 0
echo USB0 > /proc/acpi/wakeup
echo USB1 > /proc/acpi/wakeup
echo USB2 > /proc/acpi/wakeup
echo USB3 > /proc/acpi/wakeup
This will also enable wakeup from your keyboard if it's a USB one. If
you are running Ubuntu 10.04 you might need to revert to kernel
2.6.32-32 as there is/was a bug in later kernels which powered down the
USB ports when suspending and therefore breaking USB wakeup.
Ah, I've just seen in the wiki article that it addresses that problem
now in the next chapter. Something to try out for me today ;-)

That's the way I do it and I didn't solder anything.
