Tommy,
I'm running a slightly newer (and 64-bit) kernel:
$ uname -a
Linux ze 2.6.32-22-generic #33-Ubuntu SMP Wed Apr 28 13:28:05 UTC 2010 x86_64 GNU/Linux
With an older KDE (4.4.2).
And I'm not seeing the problem.
Here's a quick test to verify:
$ cat - | wc
[now look at your desktop clock (assuming it has seconds) and press some key for roughly 10 seconds, like so:]
ccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccc
[After 10 sec, release the repeated key. Hit ^D to close the input to 'cat' and look at the number of chars printed by 'wc']
I get over 500 (in this example 513) chars meaning that my repeat rate is roughly 50 cps (there's a 250ms delay at
the beginning before repeating starts). Just as my X setting is set to.
I'm also running the nvidia module for X (from /var/log/Xorg.0.log).
xorg-server 2:1.7.6-2ubuntu7 (Bryce Harrington <bryce at ubuntu.com>)
...
(II) LoadModule: "nvidia"
(II) Loading /usr/lib/xorg/extra-modules/nvidia_drv.so
(II) Module nvidia: vendor="NVIDIA Corporation"
compiled for 4.0.2, module version = 1.0.0
Module class: X.Org Video Driver
(II) NVIDIA dlloader X Driver 195.36.15 Fri Mar 12 00:38:50 PST 2010
(II) NVIDIA Unified Driver for all Supported NVIDIA GPUs
...
(**) Option "xkb_rules" "evdev"
Anyway, this combo with the kernel I use doesn't seem to have the keyboard hiccup problem.
Could you upgrade your kernel to the latest Ibex (10.4) kernel and retry?
YMMV.
