Comment 35 for bug 39315

Hello,
I have an Acer Travelmate 4000, running under latest Dapper, and am encountering a similar problem (only since I updated to Dapper, not before under Breezy). At first I did only have the "skip problem", not the "repetition problem".
I have tried the :
sudo modprobe -r psmouse
sudo modprobe psmouse rate=40
but it caused my touchpad not to work anymore. I also tried to uninstall plptools, but it wasn't installed. I rebooted, I used the embedded "Fn+F7" to reactivate the touchpad, which did work, and then tried the "i8042.nomux=1" fix, which didn't change anything and caused the "repetition bug" to happen in addition to the "skip bug".
For what I've seen, the problem also happens in virtual consoles. I've tried typing continuously and found the skips to last for about half a second, and happen every 30 seconds - could that be synchronised with the battery monitor's frequency ?
I'll try other suggested fixes, and see if something changes. Any help greatly appreciated, this problem is really annoying.
