videodev.o
	this is the basic video4linux module, all video 
	drivers (incl. bttv) register themselves here.

i2c.o
	the generic i2c module. It does much of the i2c bus
	management, all other modules (except videodev.o)
	use this one

	insmod args:
		scan=1		scan the bus for i2c devices
		verbose=0	shut up i2c
		i2c_debug=1	for debugging, it sticks the 
				whole (software) i2c bus 
				traffic to the syslog

bttv.o
	the bt848 (grabber chip) driver

	insmod args:
		remap=adr       remap Bt848 memory to adr<<20		
		vidmem=base	frame buffer address>>20 (of graphic card)
		triton1=0/1     for Triton1 compatibility
                                Triton1 is automatically recognized
                                but this might also help with other chipsets
		pll=0/1/2	pll settings
				0: don't use PLL
				1: 28 MHz crystal installed
				2: 35 MHz crystal installed
		radio=0/1	card supports radio
		card=n		card type
				0:  Auto-Detect
				1:  Miro
				2:  Hauppauge (old bt848 boards)
				3:  STB
				4:  Intel
				5:  Diamond
				6:  AVerMedia
				7:  MATRIX Vision MV-Delta
				8:  FlyVideo
				9:  TurboTV
 				10: Hauppauge (new bt878 boards)
				11: MIRO PCTV pro
				12: Terratec/Vobis TV-Boostar
				13: Newer Hauppauge WinCam (bt878)
				14: MAXI TV Video PCI2
				15: Terratec TerraTV+
				16: Aimslab VHX
				17: PXC200
				18: AVermedia98
				19: FlyVideo98 (newer FlyVideo cards)
				*20: Zoltrix TV-Max
				*21: iProTV
				*22: ADS Technologies Channel Surfer TV
				*23: Pixelview PlayTV (bt878)
				*24: Leadtek WinView 601
				*25: AVEC Intercapture
				*26: LifeView FlyKit w/o Tuner
				*27: Intel Create and Share PCI

	remap, card, radio and pll accept up to four comma-separted arguments
	(for multiple boards).  The CARD and PLL defines from the Makefile
	are used as defaults.

msp3400.o
	The driver for the msp34xx sound processor chips. If you have a
	stereo card, you probably want to insmod this one.

	insmod args:
		debug=1/2	print some debug info to the syslog,
				2 is more verbose.

*tea6300.o
	The driver for the tea6300 fader chip.  If you have a stereo
	card and the msp3400.o doesn't work, you might want to try this
	one.  This chip is seen on most STB TV/FM cards (usually from
	Gateway OEM sold surplus on auction sites).

	insmod args:
		debug=1		print some debug info to the syslog.

*tda8425.o
	The driver for the tda8425 fader chip.  This driver used to be
	part of bttv.c, so if your sound used to work but does not
	anymore, try loading this module.

	insmod args:
		debug=1		print some debug info to the syslog.

*tda9855.o
	The driver for the tda9855 stereo decoder / audio processor chip.
	
	insmod args:
		debug=1		print some debug info to the syslog.

*dpl3518.o
	Driver for the dpl3518a Dolby Pro Logic Processor
	
	insmod args:
		debug=1		print some debug info to the syslog.

tuner.o
	The tuner driver.  You need this unless you want to use only
	with a camera or external tuner ...

	insmod args:
		debug=1		print some debug info to the syslog
		type=n		type of the tuner chip. n as follows:
				0: Temic PAL tuner
				1: Philips PAL_I tuner
				2: Philips NTSC tuner
				3: Philips SECAM tuner
				4: no tuner
				5: Philips PAL tuner
				6: Temic NTSC tuner
				7: Temic PAL tuner
				*8: Alps TSBH1 NTSC tuner
				*9: Alps TSBE1 PAL tuner

i2c_chardev.o
	provides a character device for i2c bus access.  Works for 2.1.x
	only, not compiled by default.
