The two other commercially successful OSes - Windows and Solaris have 12Kb and 8Kb default kernel stack sizes. And both seem to do well (hold on :) with the large stack sizes - meaning there is no commercially observed problem created by the 8K stack size. Solaris even lets you change the kernel stack size at runtime. Even if we keep aside the impending argument about both OS'es being crap and we shouldn't be imitating them, we could still derive one conclusion from them - it is possible to have larger stack on i386 without problems (albeit with some drawbacks) which could be used under certain circumstances.
