Linux 2.6 supports something like if CONFIG_MMU is disabled which looks like it could suit your particular type of application. So far nobody has made any attempt to get this to run on MIPS but doesn't look too hard. This of course will have serious impact on userspace applications - the ABI necessarily has to change if the MMU is gone. Ralf
