Yes; in fact, the module is not documented as supported and is not
connected to the build intentionally.  The isa(4) modules in general
do not appear to be supported — if you load it after boot, the
respective device_probe method will never be called even once (note
that there is an extra device_printf in the module's aps_probe), so
it's not anything that's specific to aps(4).

If you can compile it both as a module and in-kernel, and load the
module before boot, then you can, however, unload the module when the
system is running, and then load it once again, but it seems that
after this you'll no longer be able to unload it successfully. :-)
