Only the first two appear in /sys/module/i8042 so I'll have to reboot to
try the other ones.  FWIW, I tried to `echo
Y >/sys/module/i8042/parameters/debug` and the resulting messages in
`dmesg` indicate that the kernel receives the press and release of the
mouse buttons at the right time, so the problems comes from "higher up"
in the software stack.
