It is not an ideal situation, however there are many changes in FC2 as opposed to FC1 using a 2.6 kernel.. updated glibc and a kernel built on gcc3.3.x are two huge issues.
The comments in the kernel changelog and in the LKML that I read suggest the 4K stack change was not primarily for desktop speed or response times.. it is a change to vastly improve system scalability (aimed at highly multithreaded apps such as network servers). Register Parameters may have a more direct effect on desktop performance.. the newer updates to the scheduler are actually where the best gains in desktop 'response' and 'speed' come from.
