[gentoo-amd64] Kernel 2.6.21 problem

[Peter Humphrey]

On syncing today I was offered gentoo-sources-2.6.21. On attempting to 
compile it I get:

drivers/built-in.o: In function `acpi_rtc_init':
glue.c:(.init.text+0x34c2): undefined reference to `pnp_bus_type'
drivers/built-in.o: In function `acpi_bus_generate_event':
(.text.acpi_bus_generate_event+0x25): undefined reference to `event_is_open'
drivers/built-in.o: In function `acpi_bus_get_power':
(.text.acpi_bus_get_power+0x97): undefined reference to 
`acpi_power_get_inferred_state'
drivers/built-in.o: In function `acpi_bus_set_power':
(.text.acpi_bus_set_power+0xf3): undefined reference to 
`acpi_power_transition'
drivers/built-in.o: In function `acpi_bus_set_power':
(.text.acpi_bus_set_power+0x165): undefined reference to 
`acpi_power_transition'

Does this imply that I'm required to include a full ACPI setup in my 
kernels? I'm trying to prevent all attempts to switch my monitor off, but 
without a lot of success so far. (If I haven't told the machine to do 
something, it shouldn't do it; and I want control over my peripherals 
thank-you-very-much.)

My kernel-compilation method is as follows:
1.	Emerge -u gentoo-sources
2.	Set /usr/src/linux manually (I know there is an automatic method, but 
that kills any package that's recompiled with every kernel version)
3.	Copy the previous .config from its store on /boot
4.	Make oldconfig and set any new options, making a note of any that need 
further exploration
5.	If any such notes, make menuconfig and read help; change any settings 
that need it
6.	Make && make modules_install
7.	Copy new .config and new kernel to /boot
8.	Change /boot/grub/grub.conf to choose the new kernel by default
9.	Reboot no-X and remerge nvidia-drivers and vmware-server
10.	Reboot into KDE and check the system over
11.	Celebrate with a pint.
