Welcome to the real world. This is how a lot of things are designed, 
they have absolutely no interest in you the programmer. I run into crap
like this time and time again.  Wasn't it just recently we learned that
LG was using the FLUSH_CACHE atapi command to do firmware upload?
You have my sympathies, i know what its like to want to create a usefull
utility only to find it cant be done because of the designers stupidity.
Someday, maybe, new products will go through some kind of "programmers
design review" before being released... someday, maybe.
