'comment' is already supported by make {menu,x,g}config and AFAIK by
make oldconfig too.  It is not effective in make oldconfig though
because it will scroll off the screen quickly.

I am not a friend of 'select', but maybe the following actually helps.
I didn't follow all of this and previous related discussions, so I guess
somebody else suggested something like this before:


# drivers/ata/Kconfig

config ATA
	[...]

comment "Controller drivers"

[...low-level drivers go here...]

comment "Storage device drivers"

config ATA_SD
	tristate "SATA/PATA HDD support (via SCSI disk support)"
	depends on ATA
	select BLK_DEV_SD
	help
	  'SCSI disk support' is required to access SATA HDDs.  It is
	  also necessary for parallel ATA (IDE) HDDs if you use the
	  experimental parallel ATA option.

	  You can say Y or M here to select SCSI disk support, or you
	  can do so in the 'SCSI device support' section.

[...ditto for CD/DVD-ROMs, tapes, and generic support...]
