Unfortunately, it won't work.

You can't swap control and caps lock keys with xmodmap because caps
lock key has either mechanical lock key switch (obvious and
uninteresting case) or soft lock which makes it always sticky (this
case).  Soft lock caps lock key submits its make or break code when
pressed, and submits nothing when released.  So, if you press and
release caps lock key, the computer will think it's still pressed
until you hit it again.  IOW, it's sticky.

Obviously, keyboard's built-in microcontroller does this, probably in
order to make it look the same from the computer whether it is
mechanical or soft lock.

This is exactly why I gave up on the extended keyboard that came with
my Q840AV, went to our university's surplus store, and picked up this
standard keyboard I'm using right now for $5 ;-)
