as background, can you expand on how this is useful?  i just spent
a bunch of time debugging issues with HOST_SLEEP_CFG and
HOST_SLEEP_ACTIVATE (which doesn't work on an 8388) on the XO-1
OLPC laptop, and i'm wondering whether or how this would have
helped.

as an aside, since i know you've helped OLPC with some of these
issues in the past, the pertinent results of my debugging are:
 http://dev.laptop.org/git/olpc-2.6/commit/?h=olpc-2.6.31&id=515dc7313c37218fa02888eb19fba065ca0ab63c
and
 http://dev.laptop.org/git/olpc-2.6/commit/?h=olpc-2.6.31&id=8db05fd8301980cf48ff10f61c977256e1f136b5

other nearby commits, all dated 6/22/2010, are related, but were
less central to the problems we were having.)
