That's a pity, suppressing just the message is cheating. You won't get
any further information to fix the real bug. And it definitely is a bug,
see here the "kern.log" from Hardy, where all works fine:

Jun 22 12:35:41 pp kernel: [ 54.573266] input: PC Speaker as
/devices/platform/pcspkr/input/input4
Jun 22 12:35:41 pp kernel: [ 54.589284] i2c-adapter i2c-0: nForce2
SMBus adapter at 0x1c00
Jun 22 12:35:41 pp kernel: [ 54.589302] i2c-adapter i2c-1: nForce2
SMBus adapter at 0x1c40
Jun 22 12:35:41 pp kernel: [ 54.665463] Linux video capture interface:
v2.00

and the second i2c port needs a module - probably it's the reason why
Lucid does not perform kernel-suspend correctly - as Hardy does!

While this is the error message in Lucid:
