Okay, great.

I will hold off merging the patches for a little white. We will need
to commit them some time this week though. If they are not the final
version then that is okay.

Once you have something ready for upstream, we should cc Ben H (who as
you know wrote pflash) for his thoughts. We need to do that this week
as he won't have much time next week.

Cheers,

Joel
