I wrote to Peter Osterlund, still listed on the Man pages as the author
(but he is no longer the maintainer of it.) This is his response:

"I was not aware of this problem (I don't normally use syndaemon), but I
was able to reproduce the problem on my fedora machine. The problem is
that the default keyboard polling interval is now 200ms, so keypresses
shorter than that risk being missed.

There is however an undocumented switch -m to change the polling
interval, so try running "syndaemon -i 0.5 -k -m 20", which sets the
polling interval to 20ms.

I guess this change was made to conserve battery power on laptops. It
would be better if syndaemon didn't have to poll at all, but I don't
know how to implement that, or if it is even possible.

Btw, I am no longer maintaining this driver, but feel free to forward my
response to whoever is maintaining the driver these days.

Best regards,
Peter Osterlund"

I did test it and while the "-m 20" didn't seem to make much difference,
changing it to "-m 2" did resolve the problem. However, as Peter
mentioned, it may be too much on the system to poll every 2ms.
