WITHOUT_MODULES, does it actually work?

I've been playing around with it (RC3, i386) and got it to look like 
this (/etc/make.conf):

WITHOUT_MODULES= dev/firewire dev/bwi dev/bce dev/bfe dev/iwi dev/iwn 
zfs sound/driver/ad1816 sound/driver/ai2s sound/driver/als4000 
sound/driver/atiixp sound/driver/audiocs sound/driver/cmi 
sound/driver/cs4281 sound/driver/cs4281 sound/driver/csa 
sound/driver/davbus sound/driver/ds1 sound/driver/emu10k1 
sound/driver/emu10kx sound/driver/envy24 sound/driver/envy24ht 
sound/driver/es137x sound/driver/ess sound/driver/fm801 
sound/driver/ich sound/driver/maestro3 sound/driver/mss 
sound/driver/neomagic sound/driver/sb16 sound/driver/sb8 
sound/driver/sbc sound/driver/solo sound/driver/spicds 
sound/driver/t4dwave sound/driver/uaudio sound/driver/via8233 
sound/driver/via82c686 sound/driver/vibes

Well .. I don't know what's wrong but no matter what, all of those 
modules and stuff still get built and end up under /boot/kernel ... I 
just need "sound" and "snd_hda"...

What am I doing wrong?
Any hint will help

BTW: where is Bluetooth located so I can also get rid of it?
