That was the correct address. I see your previous post. Sorry we had no
time to answer then. Greg KH must know about it too.

One preliminary note: our authority on I2C IDs isn't unquestionable.
Sometimes people submit patches to the Linux kernel and use whatever ID
they want. It's a shame but it works. So, if someone is quicker than you
to use the following IDs, we may have to concede and have you change
your IDs.

Another note: you shouldn't expect to see any of your drivers accepted
into Linux 2.4 anymore.

Here we go anyway:

#define I2C_DRIVERID_OVCAMCHIP	61	/* OmniVision CMOS image sens.	*/
#define I2C_DRIVERID_TDA7313	62	/* TDA7313 audio processor	*/

#define I2C_HW_SMBUS_OV511	0x0e	/* OV511(+) USB 1.1 webcam ICs	*/
#define I2C_HW_SMBUS_OV518	0x0f	/* OV518(+) USB 1.1 webcam ICs	*/
#define I2C_HW_SMBUS_OV519	0x10	/* OV519 USB 1.1 webcam IC	*/
#define I2C_HW_SMBUS_OVFX2	0x11	/* Cypress Ez-USB FX2 USB 2.0	*/

Greg, should I send a patch to you with these?
