Unfortunately, the device driver ABIs (and many others) are different
between 4.1 and 5.0-current so you cannot load a binary driver intended
for 4.1 on a 5.0-current system.
For newbus at least, the programming API is the same, although in 5.0 it
uses kobj for its object model instead of the slightly less flexible
system used in 4.x. You need to rebuild the driver, using makeobjops.pl
instead of makedevops.pl.
