8.2-release no sound. error "driver bug: Unable to set devclass (devname: (null))"

[Zhang Weiwu, Beijing]

Behavior:


    tobago# kldload snd_driver
    driver bug: Unable to set devclass (devname: (null))
    ppc0: parallel port not found.
    driver bug: Unable to set devclass (devname: (null))

It turns out the kldload command itself have no output. all output are from dmesg.

What can I / should I do?

Interesting section of 'pciconf -lv':

none1 at pci0:0:4:0:	class=0x040100 card=0x103b13bd chip=0x545510b9 rev=0x03 hdr=0x00
     vendor     = 'Acer Labs Incorporated (ALi/ULi)'
     device     = 'AC'97 Audio Controller (M1563M Southbridge)'
     class      = multimedia
     subclass   = audio

By the way I tried to compile a kernel without ppc driver, thinking it causing trouble. Result is:

tobago#	kldload snd_driver
driver bug: Unable to set devclass (devname: (null))
driver bug: Unable to set devclass (devname: (null))
driver bug: Unable to set devclass (devname: (null))
