I want to set the "frowning upon" aside just for the moment and point
to the fact that the symbol actually is exported and in consequence
should be described by some data type. The data type may be "totally
architecture dependant".

I can join the frowning upon if we extend it to be about the export
of the sys_call_table in the first place, but there are no other means
to populate a syscall from a module, or have I missed something?

The different AFS implementations have used this for years.
