Is there any benefit to actually disabling this stuff?

IMHO device operation modes (for ex., AHCI/legacy IDE for SATA, LPT port 
modes, etc) should be in CMOS. Also switches for enabling/disabling 
devices (LPT, FDD, IDE/SATA, etc) should be in CMOS.

Kconfig vs. devicetree vs. CMOS policy for options?

Sometimes it's necessary, like in the case of disabling integrated
graphics to allow a PCI/AGP/PCIe card to work. Other times, like
disabling ps2 and floppy devices, it shaves a little time off bootup,
because neither coreboot nor the guest OS have to do init for
non-existent devices. Still others it's just convenient, like
disabling a problematic or slow onboard NIC or poor quality audio
device, again in favor of another board.
