With the old CreatePixmap API, drivers could override the width and
height when calling down to prevent the fb layer from allocating the
pixmap memory, and then plug in its own. It looks like a driver could
do the same thing now by changing the pixmap structure's width and
height to 0 temporarily, but it looks like that will cause the new code
to call malloc(0) and then fail if it returns NULL.
Might make sense to have the fb code *not* allocate memory if
devPrivate.ptr is non-zero?
Oh, you mean have the driver allocate the storage before calling down?
Yeah, that's a good idea.
