BTW: except this problem, 2.6.14 with 16k page size runs well on my machine. According to our experiences of 2.4 kernels, 16k page size has a bit benefit over 4k page size(average 6% improvement for spec cpu2000 int). But to use 16k kernel, we have to convert binaries of debian/mips: their sections are often not 16k aligned untill the latest testing branch.
