Hi Berthold,

I'll send it to you by mail. ( anyone else? :-) )

With the kernel < 2.6.12 i used the acpi-ec-nospinlock patch included in Richs 
sbs-package. Later i had to use the ec-burst patch from Luming Yu from here:

http://bugzilla.kernel.org/attachment.cgi?id=5574&action=view

Then I have to pass ec_burst=1 as kernel parameter. Without this my machine 
misses keystrokes when I'm typing "fast". (I use this with a 2.6.13 vanilla 
kernel)

Perhaps this has to do with the flex version on you machine. I've read about 
some problems due to a too recent version of this package. I'm using gentoo 
so I'm not sure, but there seems to be a flex-old (or something like that) 
for debian with which you may have more luck getting iasl compiled.

Yes but this even happens if you recompile a "unchanged" DSDT. So the produced 
code is not usable I'm afraid.

I'm using my patched dsdt since february this year and the battery status is 
working without any problems on different kernel versions. The only issue i 
had was the missing keystroke problem. BTW. I'm using the acpi-dsdt-initrd 
patch for "feeding" my dsdt to the kernel.
