Thanks Lucas,

now acpi works fine, but I have always problems with my sound card!
How can I know if /dev/dsp exists? aumix works whitout errors...
I think drivers are installed properly, but there's some kind of problem 
with initialization. If I start the system with the liveCd the message 
appears too!
