acpi and sound

hi,
i am running fbsd current on asus m2400n laptop. acpi works pretty fine
there but i am unable to get sound working. i am wondering whether this
could be and irq/acpi problem ?
when i load the sound module (guess snd_ich would be the correct one) i
get the following error:

$ kldload snd_ich
$ dmesg | tail
Mounting root from ufs:/dev/ad0s3a
pcm1: <Intel ICH4 (82801DB)> port 0xe100-0xe13f,0xe000-0xe0ff at device
31.5 on pci0
pcm1: unable to map IO port space
device_probe_and_attach: pcm1 attach returned 6

i look in the code and found out that my sound card/chip set should be
supported.

any hint what i could try else ?

thx 
seb

ps: some more info:
