Intel 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller with netbsd 4

Hi.
I just installed netbsd 4. on my laptop, and I have two options :
1. I use generic kernel but it hangs after the boot process at the point 
"kernelized raidframe activated"
2. I use noacpi kernel but my sound card hangs with the message :

   *
     pci_intr_map: no mapping for pin D (line=ff)
   *
     cbb0: couldn't map interrupt
   *
     pcib0 at pci0 dev 31 function 0

   *

It seems that's it's an old bug. Any idea on how to have my audio card 
work ?
Thanks in advance.
Best regards,
