unknown symbols errors when using OSS or ALSA USB Audio devices in official 10.03 Backfire builds

Description
USB Audio devices fail to work in the 2.6 backfire builds on broadcom hardware, not sure if other architectures are affected. A large number of 'unknown symbol' errors relating to audio functions are reported by dmesg upon plugging in an audio device.
Note building your own backfire image from svn with audio modules linked at compile time works correctly, seems to specifically be a problem with the build config for the official builds.
Hardware is Asus WL-500gP V2, another user reports the same problem on the wgt634u. See here for further backround:

Key modules installed:
kmod-usb-core
kmod-usb2
kmod-usb-ohci
kmod-sound-core
kmod-usb-audio
dmesg output attached

Can you confirm you're still experiencing this issue on 10.03 final ?

- Component changed from base system to kernel
- Owner changed from developers to nico
- Status changed from new to assigned
- Version changed from backfire 10.03 RC1 to Backfire 10.03
Confirmed on an Asus WL-HDD (brcm47xx) running 10.03.
It seems 'kmod-sound-core' depends on 'kmod-input-core'.
