If you look at the VSC7385 switch product brief:
   <http://www.vitesse.com/products/product.php?number=VSC7385>
you will see that it has a 8051-type supervisor processor.  It looks to 
me like all Timur is doing is loading a binary blob into the switch's 
supervisor processor, which would not be a GPL issue.

Unfortunately, Vitesse feels their loader software is sooper sekret so I 
cannot download a copy to see what the licensing terms are.  If that is 
_not_ GPL, there may be an issue, but only with the loader software.  If 
the loader software is stand-alone (can be run as a u-boot stand-alone 
application) it would not be a GPL issue since the u-boot license 
explicitly allows that.

IANAL (and have been reading too much groklaw)
