cgd eb4cd26383 from the comments at the top of the file:
INSTALL -- somewhat generic kernel with a snowball's chance of
	   fitting on an install floppy.

This kernel MUST consist (for users' sanity) of a subset of
the GENERIC configuration.  It also should support X reasonably
(though the SysV SHM extensions won't work).

To avoid a maintenance nightmare, this kernel consists of GENERIC
with missing options/devices/etc. REMOVED rather than commented
out.  That makes it easy to diff agains GENERIC, to make sure that
it really is a subset of the functionality.

cgd aeb93da3d7 Split FFS,QUOTA line, comment each individually.
Add 'options INSECURE' so that the GENERIC kernel is happy with
X's linear mapping.
