As I read on the list, there are also other notebooks, that have 
problems with suspend under kernel 2.6.25-rc?.

So today I installed and tested kernel version 2.6.24.4 with the 
exchanged DSDT.

And so far everything seems to work now.
I can boot the system with ACPI enabled and suspend is also working.

If anyone needs a working DSDT and .config for kernel 2.6.24.4 for a 
Panasonic Toughbook CF-52 he can just contact me.


Bye Ralf
