No luck at SPI reflash

[Mitch Bradley]

We have been having a lot of problems with this procedure lately.  It 
works flawlessly on my system, but seems to die for everyone else.

I have usually been able to walk people through some mitigation 
procedures, though.  Can you go on IRC?  #olpc  .  If so, I can take you 
through it the hard way.
