I made a table awhile ago as to which entry points are being used by
what. Most of the entry points are indeed only being used by those
other drivers which exist mostly to support a debugging tool called
vcdbg(which I didn't find that useful).

The other drivers are small drivers, but I'm not sure bringing them
here makes much sense either especially since they are mostly to
support that debugging tool. Which complicates things because probably
half the driver could be otherwise deleted instantly.

I attached a list of driver exports and which drivers are using them.
