I had tested this change against 2.6.13-rc2-mm1, and it worked perfectly as
expected, but it caused problems in today's 2.6.13-rc2-mm2 release.  For
some reason, the symbols don't get set properly.

What I meant was the CONFIG_DVB_LGDT3302 , etc flags

Previous patch removed the #define's that you see below... This should have worked, since these should be set instead from kconfig, but it didn't work as expected (even though the modules ARE selected by kconfig),
Strange... I did allyesconfig and preprocessed source shows lgdt3302.h,
or51132.h et al. are included. What's your .config?

and the #ifdef's return false.... (I don't know why it worked in my test against 2.6.13-rc2-mm1, but it doesn't work in -mm2, and it must be fixed) Breaks all hybrid v4l/dvb boards.
Everything does get built, just as you say... However, there is code inside cx88-dvb.c and saa7134-dvb.c that is enclosed within #ifdef's ... This code is NOT included during the compile. For some reason the #ifdef's are turning up as false during compile time... In -mm1 this didn't happen. For now, I am just setting these to true at the top of the *-dvb.c files... In the future, we (v4l) will either provide a better solution, or just remove the #define AND #ifdef's alltogether... I am including an excerp from cx88-dvb.c to illustrate what I am talking about:
#if CONFIG_DVB_MT352
# include "mt352.h"
# include "mt352_priv.h"
#endif
#if CONFIG_DVB_CX22702
# include "cx22702.h"
#endif
#if CONFIG_DVB_OR51132
# include "or51132.h"
#endif
#if CONFIG_DVB_LGDT3302
# include "lgdt3302.h"
#endif

<snip>

#if CONFIG_DVB_MT352
static int dvico_fusionhdtv_demod_init(struct dvb_frontend* fe)
{
	static u8 clock_config []  = { CLOCK_CTL,  0x38, 0x39 };
	static u8 reset []         = { RESET,      0x80 };
	static u8 adc_ctl_1_cfg [] = { ADC_CTL_1,  0x40 };
	static u8 agc_cfg []       = { AGC_TARGET, 0x24, 0x20 };

<snip>

static struct mt352_config dntv_live_dvbt_config = {
	.demod_address = 0x0f,
	.demod_init    = dntv_live_dvbt_demod_init,
	.pll_set       = mt352_pll_set,
};
#endif

<snip>

This should be enough to explain what I am talking about... Of course this is just a small snippet...
There is more in cx88-dvb.c that does this, as well as saa7134-dvb.c...

In -mm2, the code inside the #if is NOT compiled... This is a problem, and this is why I sumbitted the patch.
