Behaviour confirmed.

Confirmed, too.
I tried to track down the problem. I found out that XFree86 spends
lots of time in ps2Reset() at /hw/xfree86/input/mouse/pnp.c.
My pointer-device was configured to take data from gpm:
Section "InputDevice" Identifier "Configured Mouse"
Driver "mouse"
Option "CorePointer"
Option "Device" "/dev/gpmdata"
Option "Protocol" "PS/2"
Option "Emulate3Buttons" "true"
Option "ZAxisMapping" "4 5"
EndSection
After changing the device to "/dev/psaux" _and_ stopping gpm, the problem
went away.
My /etc/gpm.conf looks like that (with package version 1.19.6-12.1):
device=/dev/psaux
repeat_type=raw
type=ps2
Something in the communication between gpm and X goes wrong.
CC set do Maintainer of gpm.
