Issue with sunffb driver and Creator 3D in Sun Ultra 10
I did a fresh install of OpenBSD 6.2 sparc64 (since upgraded to 6.3)
on my Sun Ultra 10. This machine contains a Creator 3D frame buffer.
When starting X without a xorg.conf present, the Creator 3D gets
correctly recognized and the sunffb driver is loaded. At this point
the screen freezes (with some random yellow horizontal lines added),
but X seems to start normally. I can SSH into the machine (and reboot
it from console; Ctrl-Alt-Backspace doesn't work to kill X at this
point) and according to the Xorg.log (see below), everything seems
fine from X's point of view (but the screen remains frozen forever).
I did try different xorg.conf settings based on examples found online
(setting BusID manually, disabling HW acceleration, etc.), but the
result is always the same. For reference, this machine was working
normally with the sunffb driver with some very old Gentoo install
