Sure there is. Write a small TSR that traps INT 09H and looks at each keypress.
If it sees the scan codes for the NumLock or CapsLock keys, it just resets
the keyboard and the 8259 and returns. Otherwise, it would pass the key on
to the BIOS keyboard handler. The startup routine for this TSR could set
the NumLock and CapsLock bits (40:17) to the desired values.
