thinkpad z60t and sound problems

[Victoria]

Hello,

i'm using freebsd 6.1 prerelease on my new laptop ibm thinkpad z60t. All works fine except sound. I can't get it working. I have tried everything and now i stuck. In kernel i have enabled sound, but i can't find any pcm devices in dmesg...
Maybe someone has success expierence with freebsd on such laptop? Please help me...
I don't want install anything other on it...

Thank You!
