sure, btw i think CONS_SETKBD is easy. nothing seems to calling it
from the kernel, so we could (intptr_t *) cast it and it should just
work. i really want to change it to

#define CONS_SETKBD     _IOW('c', 110, int)

because i officially hate _IO() now :) but i'm not sure if this breaks
binary compatibility.

me makes a mental note to never ever use _IO() anymore.
