	Also, modules go into *different memory* than kernel memory.  When
accessing them, they take a little longer just to run, due to page
faults.  I've seen estimates of up to 5%, depending on the kernel hacker
you're speaking with.

	Modules do take up a bit more memory than the compiled in versions. 
So, if you're always gonna use X, then compile it in.

	On the other hand, if you're a distributor like RedHat, then you want
your shipping kernel to work everywhere.  So, you make everything you
can a module.  It Just Works!
