Nope. The arch number specifies what kind of arm-board the kernel is
booting on. One kernel binary is in my case able to handle 3 different 
versions of boards (and its hard or dangerous to find out by probing
the board). The number is used to tell the kernel about how irq-lines
etc are wired on the board. Perhaps the name 'arch' is a bad choice, 
perhaps "arm-mach" is better.
