Good point :)

The Kconfig system doesn't presently know the name of the module,
but that could be added.  eg:


  config BMAC
	tristate "BMAC (G3 ethernet) support"
	depends on PPC_PMAC && PPC32
+	modulename bmac
	select CRC32
	help
	  Say Y for support of BMAC Ethernet interfaces. These are used on G3
	  computers.

-	  To compile this driver as a module, choose M here: the module
-	  will be called bmac.


Any sane organisation would look at the benefit of this, weigh that
against the massive amount of code churn and would then run away howling.
