Thanks for reporting. The warning did not show on my 32-bit x86 system,
and I guess it did not show on Wolfram's system either, otherwise we'd
have fixed it.

Does the following patch fix the warning for you?

--- linux-2.6.32-rc8.orig/drivers/misc/eeprom/at24.c	2009-11-26 09:14:45.000000000 +0100

If it does then I'll merge this into Wolfram's patch.

Thanks,
