Solaris' lkm is quite similar to Linux modules and you can load and 
unload them quite the same.

The problem with unloading is locking. If you go beyond single core 
single threaded, you need locking, and if the code breaks and leaves the 
locks "on" you can not fix it by simple umload+load.

So unloading works when the modules are bugfree or at least don't step 
on some lock.
