It is not very clear to me why you'd want to.  Using XFree86 on a port
like sparc that doesn't have to deal with the endless ranks of almost
but not quite identical video cards that plague PCI (and earlier ISA)
systems is madness.  With that kernel driver, about the best you're
going to get is a dumb depth-24 framebuffer anyway (= slow).

But even if you insist, there are a couple of points I can speak to.

> Have I to use the /dev/fb device?

Maybe.  Which screen do you want X on?  /dev/fb _should_ give you the
cg14, based on the boot messages.

> If so, the X server is comming on the non-sonsole card, ie cgsix0.

Ugh.  Must be something bizarre with XFree86's device enumeration.
(Another reason not to use it; having the X server do its own bus
enumeration is further madness.  I conjecture that this is partly at
fault, that XFree86 doesn't know about obio, only sbus, and thus thinks
you have only the one framebuffer.  Another conjecture is that it found
the cgfourteen but doesn't know how to do anything with it.)

No.  /dev/cgfour0 is for the cgfour, a framebuffer that dates back to
the Sun-3 days.  You need to create /dev/cgfourteen0 (or some
equivalent).  On past systems I could have told you how to work out the
major number you need, but I don't understand the current
device<->driver attachment scheme well enough.
