__init and __exit vs module_init()

[Dan Erickson <coldoneknight@rogers.com>]

	Howdy,
		
	 	What I am wondering is, is __init equal to module_init()?
	Basicly... I was confussed as to what happens if you want to 
compile a driver directly into the kernel. Then I discovered __init.
	There needs to be some way the kernel knows what the entry point 
of the driver is, and if you have module_init() everything is all well and 
good, the kernel is happy as it knows what the entry point is, but what if 
you dont compile as a module? Then all of a suddenly the kernel doesnt 
know what the entry point is because all you have given it is the entry 
point "IF" it was compiled as a module. Is the purpose of __init to tell 
the kernel the entry point in the event that the driver is compiled 
directly into the kernel?
	The best answer I could get would be from "Linux Device Drivers" 
by Oreilly. Though I found there explanation cryptic.

Thanks for the help
