The problem is that the xf86_use_hw_cursor(_argb) functions may get this
correctly now, some drivers will replace these generic versions with their
own functions. It is pretty insane to expect them to do reference counting
of the cursor (as an example, look at driver/xf86-video-vmware to see how
that looks like as a workaround). There are even places in xserver itself
which replace these two functions.
The segfaults if no reference counting is done are caused because the
reference count of the cursor reached zero, hence the cursor was freed,
however xf86CursorEnableDisableFBAccess() brought it back to life from
the dead (from the SavedCursor).
This patch hence adds reference counting in xf86CursorSetCursor. As per Michel
Daenzer's suggestion, also free the cursor upon xf86CursorCloseScreen.
In theory with this it should be possible to remove the reference
counting in the UseHwCursor functions I think, though it should also be
safe to keep them.

you know the dependency better than I do so any hints are apreciated.
afaict, the screenInfo.numScreens (the check used by Xinerama) isn't
necessarily initialized at this point so we can't use the same check.
The following seems to work though:

Subject: [PATCH] xfree86: if only one screen was found, disable Xinerama (#24627)
Xorg +xinerama crashes immediately due to whacky dependency between Xinerama
and RandR12. The latter doesn't initialize if Xinerama is enabled, but if
only one screen is found, Xinerama is disabled again and RandR12 tries to
access data it never initialized.
Dependency chain is:
- ProcessCommandLine sets noPanoramiXExtension to FALSE
- xf86RandR12Init() is a noop
- PanoramiXExtensionInit sets noPanoramiXExtension to TRUE
- xf86RandR12CreateScreenResources tries to use the devPrivates key it never
initialized.
This hack checks if there's only one screen at the time RandR12 is
initialized. If so, we expect Xinerama to fail anyhow so we disable it
ourselves and proceed as planned.

Technically, disabling AEI is the right suggestion. AEI off forces the
server to init the built-in defaults for input devices (or pick the first
one from the config file). At the same time, hotplugging is still available
with AEI off.
Unfortunatly, in the vast majority of cases users want to simply disable
hotplugging or have a working server while the local HAL configuration is
broken or missing. Disabling AEI will lead to duplicate events, triple
keystrokes, etc. once the configuration works again.
It's not actually required to remove AEI once hotplugging works again,
though it will in many cases lead to a setup that appears broken.
Asking users to disable AutoAddDevices instead means those users disable
hotplugging, can then fix the HAL setup and they _must_ remove the config
line again to test if hotplugging works again. Which doesn't leave them with
a broken config once everything is working nice and dandy. Less bugreports,
everybody wins.
