Actually, people who want to run Linux on laptops instead of MS care a
whole bunch! And not everyone has a committment from their employer to
provide Linux compatible hardware, or the personal funds to spend extra
to buy their own instead of getting a bargain laptop which may not be
fully supported. 8KSTACKS is in and working, you are proposing to break
Linux on a number of machines just to satisfy some personal distaste for
the code, not because there is neat new code which fails to work with 8K
stacks.

You must have something more useful to work on, which would ADD value to
the kernel instead of breaking existing installations. Ripping out petty
stuff which works is a waste of your time and talent, please find
something better to do. Perhaps devise a way for programs like
ndiswrapper to provide their own stack, for instance.
