The arm branch Kconfig was updated awhile back to include auxdisplay.

I have been messing with a couple LCD devices similar to the cfag12864.
Every time I update my kernel source I have needed to add this patch
since my arm platform does not have PARPORT_PC.

That was my stimulus for the patch.  It does cause the empty menu to
appear but some others already do that so I didn't think it was a
problem.

Hartley
