yes, this is correct. these programs masquerade as "kfs" to make the boot
process happy.

on many motherboards, ps/2 keyboard and mouse are emulated by bios.
when usb is turned on, then the the bootloader or os (perhaps via bios calls)
needs to deal with usb.
i think that the distribution usb is not working for some ehci chipsets, especially
those that need explicit bios handoff, and those with multiple ehci controllers.
