I'm assuming you mean RHEL, not Red Hat Linux 7?

if there is an ABI conflict at load-time then you're not compiling against
the correct X server header files. make sure you have xorg-x11-server-devel
installed and you're compiling against those headers.

also note that the xf86 joystick driver doesn't use js0, it uses the evdev
nodes. It's not a joystick driver as such, it's a driver for those that want
to use their joystick as a mouse replacement.

huh? if you get an ABI mismatch on the module you would get the same ABI
mismatch when running against event nodes. This check is done way before the
driver checks what device it is set up for.

best to file a bug, without an Xorg.log it'll be hard to debug any further.
