ok, i will place them into mfp-pxa168.h. I just thought it is not prefered
to change the mfp-pxa168 file.

i would very glad to make them in small patchs. i am just now on travel,
and will do that in several days when i am back.

AC97+UCB1400: Sound and Touchscreen is ok. The related pxa2xx-ac97 files
have to be modified, the changes are not in this patch. If u want, i can
patch them later too.
