Hmm. Setting it down to 256 on x86-64 does cause a fair number of 
warnings even for something like my personal build (that avoids all the 
crazy drivers etc), but it looks "manageable" - ie something where a 
kernel developer should try it, and fix all the ones that they maintain.

And if you don't get any warnings in your area, try lowering it to 100 or 
something.
