For now i didn't get it to work. But now i already heard sound with that
kernel. There happend some mistakes with the grubscripts in /etc/grub.d/ and i
bootet my LFS-kernel with my Ubuntu-root-partition and i heard the startup
sound of the XServer! So i think my the drivers for my sound card are working.
So on the other hand: Now i know tha's not the problem and i have to search
for something else. :(
