 Doesn't matter if I stop OFW with esc and type "boot" or just let it try
 and automatically boot... if the 8787 dev kit is plugged into the external
 SD slot, the boot never happens (and no more output is seen on the serial
 line).   This happens with recent OFW on both XO-1.5 and XO-1.75.

 Workaround suggested by Cerlyn and pgf on irc works fine on both XO-1.5
 and XO-1.75:

    add-tag BD int:\boot\olpc.fth

 Deployments aren't likely to be plugging dev kits into SD slots, but this
 bug suggests OFW could use some more robustness in how it takes its first
 look at devices plugged into the external SD slot, because users in the
 field might put other strange or malfunctioning devices in, and having OFW
 mysteriously hang and fail to boot is not good.
