2.6.2 PPC ALSA snd-powermac

Is it just me or does 'make menuconfig' in kernel 2.6.2 on ppc not give
me an option to enable i2c? It's supposed to be in Character Devices,
no? The ALSA snd-powermac module needs i2c and upon a 'modprobe
snd-powermac' spews forth:

Feb 10 17:47:25 chocomel kernel: snd_powermac: Unknown symbol
i2c_smbus_write_block_data
Feb 10 17:47:25 chocomel kernel: snd_powermac: Unknown symbol
i2c_add_driver
Feb 10 17:47:25 chocomel kernel: snd_powermac: Unknown symbol

Thanks.

Now I do understand the problem.

Short version:
It should work if you try 2.6.3-rc3 instead.

Long version:
arch/ppc/Kconfig didn't use drivers/Kconfig in 2.6.2 and didn't inclide 
drivers/i2c/Kconfig.
In 2.6.3-rc3, arch/ppc/Kconfig uses drivers/Kconfig.

Yes, it is there IIRC (I'm not at home, I can't verify). But I don't know
if the official kernel is up to date with all macintosh stuff. I'm using
2.6.2-benh1 and the option to enable i2c exists and works fine.
