>Description:

	Any kernel with option FAILSAFE turn on will not work without
	ncrcontrol.c compiled with FAILSAFE (or for that matter ANY
	other options that change the size of the struct ?cb {} in pci/ncr.c
	or the version of the NCR driver.)

>How-To-Repeat:

	Compile a kernel with -DFAILSAFE.
	try to run ncrcontrol and fails with:
	"ncrcontrol: incompatible with kernel. Rebuild!"
	recompile ncrcontrol with -DFAILSAFE and it works.

>Fix:
	
	I don't know.
	Any way of Having ncrcontrol look at "INCLUDE_CONFIG" in the kernel?
	And regen itself?  (I doubt it)

	Maybe change the error message to be more like:
	"Size of ncr kernel structures differ from running kernel? Check
	 running kernel options to insure ncrcontrol is compiled with identical
	 settings?"
