Radoslaw is right that the terminal support functions like putchar(),
cursor(), etc. are currently implemented in a the hardware-dependant
part of ite, e.g. ite_cl.c for CirrusLogic.

But Michael is also right that the code already exists. No matter if it
is in ite_xx.c or in grf_xx.c, we can copy most of it to implement the
wsdisplay support functions. And we just do that in grf_xx.c this time.

Can we come back to the real problems? :)

Question: Does XOrg's wsfb expect the mapped frame buffer to have the
same resolution as the wsdisplay console had before?
