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.
thanks,
