Cool!

So, maybe what we should do is start producing a 16M flash image suitable
for use as an iOpener root fs with the normal distribution :-)  Alternatively,
one could use sysinst to rewrite the flash with a suitable root FS.  Sadly,
sysinst doesn't really have a good way to deal with "just root on here, please,
I'll put usr on NFS..."

I really wanted to fix this with the config_pending stuff, but while it
more or less works for e.g. CardBus and PCMCIA, it doesn't work for USB
because the USB code is constructed such that it decrements its pending
configuration as soon as the first device is discovered on the USB.

This loses, since once a hub is discovered, it then asynchrously does
discovery on all the hub ports.

Maybe when a hub is discovered, it should increment config_pending for
each port that it has... that might be enough to defer mounting of the
root FS until e.g. the USB Ethernet is found.

Yah, I gotta head down to CC soon :-)
