I'm trying to get a -CURRENT MP kernel going on my HTT P4 system.  I 
have one from August 22nd, and updated my copy of cvs this afternoon.  I 
was able to build distribution, but when I went to build a newer kernel, 
I get:

#      link  SORROW.MP/netbsd
ld -T /usr/src/sys/arch/i386/conf/kern.ldscript -Ttext c0100000 -e start 
-X -o netbsd ${SYSTEM_OBJ} ${EXTRA_OBJ} vers.o
pci_machdep.o(.text+0x2a): In function `pci_attach_hook':
: undefined reference to `mpacpi_pci_attach_hook'
*** Error code 1

Stop.
make: stopped in /usr/obj/sys/arch/i386/compile/SORROW.MP

Any ideas on how I can get this working?
