Embedded controller problems

[Jorgen Bodde <solidstl-qWit8jRvyhVmR6Xm/wNWPw@public.gmane.org>]

Hi List,

I own an Acer Travelmate 4001WMLi, and after getting the battery readout 
fixed under linux by patching my DSDT file and appending it to initrd, I 
am suffering from missing keys.

Now, this phenomenon is not new to me, I knew my laptop has this under 
Windows as well. I have been trying to minimize this problem to no avail.

It just happens that every 20 characters or so, I miss out on one or 
two,. Very annoying when typing a password, and especially when SETTING 
passwords.

I have read it had to do with the embedded controller and lost 
interrupts when the battery status is polled. I also read somewhere the 
polling interval is rediculously high (every 1 second) when windows 
polls this with a less interval which can be the reason the missing keys 
are less frequent under windows.

Is there a way to lower the polling interval of the battery, or even 
better, fix this problem? My system info:

Suse 9.3
Kernel 2.6.11
Acter travelmate 4001WMLi
Panasonic battery

Any help is very much appreciated as I really would like to use Linux, 
but the missing keys make it hard to enjoy using it :-(

Regards,
- Jorgen
