I'm not 100% percent sure about this, I don't have my ASM manuals with me:

If you flip the appropriate bit (in the keyboard status byte), when the
keyboard interrupt executes, it checks that byte.  That should effectively set
the caps lock/numlock/scroll lock keys.  This probably won't flip the light on
the keyboard, but should work.
