V4L2-based build error

If you configure V4L2 as a module, the config system will still let you
configure DVB_CORE built-in. This yields:
drivers/built-in.o: In function `v4l2_i2c_drv_attach_legacy':
tuner-core.c:(.text+0x901d5): undefined reference to `v4l2_i2c_attach'
drivers/built-in.o: In function `tuner_command':
tuner-core.c:(.text+0x91aed): undefined reference to `v4l_printk_ioctl'
I never had trouble with this before 2.6.26-rc2. I'm happy making
DVB_CORE modular, but it would be nice if the config system didn't allow
inconsistent setups.

P.S. As I was digging into this, I ran into <media/v4l2-i2c-drv-legacy.h>,
which takes an interesting approach - function definitions and
module_init() within a header file? This thing is included in a
number of places; it seems like there should be a better way...
