Comment:

 it seems that the enable bit for EC runtime interrupts (and also for the
 ebook switch, though no one has noticed that yet) is being reset during a
 suspend/resume cycle.

 running these commands after a wakeup gets things working again.
 {{{
         echo enable >/sys/firmware/acpi/interrupts/gpe01   # enable EC
 interrupt
         echo enable >/sys/firmware/acpi/interrupts/gpe0A   # enable EBOOK
 interrupt
 }}}

 i don't know why these bits are getting reset.  the lid switch is handled
 almost identically to the ebook switch, and it doesn't have this problem.
