1) MAKEDEV does NOT build device drivers.
it only creates handles in the file system used to access devices.

2) there already is a device driver for the Retina Z2. It provides=20
console terminal support (ite; -> /dev/ttye1) and normalized color map
and video mode setting functions (grf1). Additionally, it allows to
mmap() the graphics boards registers and frame buffer window. However,
as this frame buffer is only accessible partially at each given time,
the X server has to know how to handle it; this is why Xamiga doesnt
work with it.

If you want an X server for the Z2, get the old Xamiga-retina2 or howev=
er it
is called exactly, and, maybe, recompile it, or integrate the hardware
dependant parts of it with the X11R6.1 (or 3) X server sources and
keyboard/mouse routines.
