That removes the ability to legally use this chipset in regions other 
than the one its designed for.  We tend to forget that a set of masks 
to make a chip, in the currently fabbing 90nm process, can ran as high 
as 50 million dollars for the more complex stuff.  And it can only 
multiply when 45nm and even 15nm come online in the coming years. Such 
precision costs money, and must be recouped by sufficient volume of the 
single chip that mask set makes.

If Litchenstein has a different set of rules, I guarantee that there 
will NOT be a seperate chips masked out just for Litchenstein.

Sure, thats so ridiculous an example its sublime, but those are the 
facts that the chip makers must deal with on a global scale.  Its much 
easier for them to furnish a binary only driver that enforces the rules 
for the region where the chip will be used.  Economically, its the only 
choice they have.  I'd be interested in how, if they supply binaries 
that could supposedly be downloaded to anyplace on the planet, do they 
enforce in software the miriad variations of the rules.  It would have 
to have some means of discovering where it is in order to enable the 
proper subset of those rules.  That however, is also proprietary info 
because of the potential for hackability if the method were known.

stupid bounce rules.  I do use spamassassin too. :-)
