audio and ethernet problem on on acer aspire 4740G

[Stellar]

well finally i have the courage to buy new notebook just for the sake of loving the bsd ,i planned to have freebsd 8(stable) as my notebook desktop,configuring my openbsd console as gateway was quite hard but this getting freebsd to detect my hardware even harder lol,getting the xorg up and running was quite easy but i really have no idea how to trace my unrecognizable devices(audio & ethernet) from dmesg?do i need to turn off my acpi first?
my notebook spec :
