Comment:

 The wakeup.patch attachment shows a proposed change to the LinuxBIOS
 startup that will reenter Linux after a wakeup.  It compiles, but is
 otherwise untested; I'm posting it early in case someone wants to get
 started early while I'm in Taiwan.

 Notes:
 a) This is probably not the right place to put the code.  It should be in
 a separate file that is included in auto.inc .  If someone could show me
 how to do it that way, I'd appreciate it.

 b) For fast wakeup, you need to eliminate early startup messages.  The
 first step is to dial down the loglevel - see *_LOGLEVEL in
 targets/olpc/rev_a/config.*.lb .  3 seems to be a good choice to eliminate
 the early messages.

 c) The other message that needs to be removed is print_err("done
 cpuRegInit\n"); in src/mainboard/olpc/rev_a/auto.c
