Problem compiling 2.5.6-pre2 w/ OSS support

[Max Kamenetsky]

Hi!

I'm having a problem complining 2.5.6-pre2 with OSS support.  If it
matters, I'm compiling support for a Turtle Beach Fiji card as a
module.  The compilation bombs out during "make bzImage" at this point:

ld -m elf_i386 -T /usr/src/linux-2.5.6-pre2/arch/i386/vmlinux.lds -e stext arch/i386/kernel/head.o arch/i386/kernel/init_task.o init/main.o init/version.o init/do_mounts.o \
        --start-group \
        arch/i386/kernel/kernel.o arch/i386/mm/mm.o kernel/kernel.o mm/mm.o fs/fs.o ipc/ipc.o \

        net/network.o \
        --end-group \
        -o vmlinux
sound/sound.o: In function `sound_alloc_dmap':
sound/sound.o(.text+0x36d9): undefined reference to `virt_to_bus_not_defined_use_pci_map'
make: *** [vmlinux] Error 1

The same problem was exhibited by 2.5.5.  I have been unable to figure
out why this is happening, so any help would be greatly appreciated.

Thanks,
