Hmm.  Lots of possiblilities, but a few things to look at:

 - Did you do a buildkernel or a make cleandepend && make depend && make?
 - Look at the timestamp on mps.o in your kernel build directory
 - touch mps.c, rebuild your kernel, and look to see that it got built
 - 'grep io_cmds_active *' in sys/dev/mps, and make sure the patch got
   applied.
 - make sure you installed the kernel in the right place
 - make sure you booted the correct kernel (look at uname -a to see when it
   was built)
