pm-hibernate & "wake up in 5 minutes"?
 
Is there a way to tell the computer to hibernate and wake up in 5 minutes (for example)? If not, asking it to wake up immediately would also be of interest.

Thanks.

There used to be the file
/proc/acpi/alarm, in which you can write the wake up time. So, the suspend script can write there before going to sleep. It's missing in more recent kernels, replaced by the file
/sys/class/rtc/rtc0/wakealarm
