undefined symbols configuring PCI for 8xx

Hello All,

I'm using linux-2.4.2 from kernel.org for a custom 8xx board.
A grep of autoconf.h returns:

grep define include/linux/autoconf.h
#define AUTOCONF_INCLUDED
#define CONFIG_EXPERIMENTAL 1
#define CONFIG_PPC 1
#define CONFIG_8xx 1
#define CONFIG_SERIAL_CONSOLE 1
#define CONFIG_MACH_SPECIFIC 1
#define CONFIG_PCI_QSPAN 1
#define CONFIG_PCI 1
#define CONFIG_BINFMT_ELF 1
#define CONFIG_KERNEL_ELF 1
#define CONFIG_PCI_NAMES 1
#define CONFIG_EXT2_FS 1
#define CONFIG_PARTITION_ADVANCED 1

After updating the qspan_pci.c file based on the prep_pci.c, I got
undefined symbols related to the CONFIG_PCI code:

make: *** [vmlinux] Error 1

The above mentioned functions are all in arch/ppc/kernel/pci.c

Is there a proper resolution to these undefineds?  I found the definitions
in prom.c, but after seeing some static globals in find_path_device, I'm
not sure I just want to include that file in the make.  Of course, I
tried, and ended up with a:

Kernel panic: Attempted to kill init!

The only idea I have know is to #ifdef out the call to find_path_device in
arch/ppc/kernel/pci.c and to not compile in prom.c, but to copy
get_property() to my xxx_setup.c with an "#include <asm/prom.h>" there.

Thanks for your help, in advance.
