With kernel.org Linux 2.4.27, we added the patch http://khali.linux-fr.org/devel/i2c/linux-2.4.27/linux-2.4.27-i2c-2.10.0 -drivers-i2c.diff <http://khali.linux-fr.org/devel/i2c/linux-2.4.27/linux-2.4.27-i2c-2.10. 0-drivers-i2c.diff> , because it was pointed to by lm_sensors http://secure.netroedge.com/~lm78/download.html <http://secure.netroedge.com/~lm78/download.html> But it empties out init_i2c_all() in drivers/char/i2c-core.c. Which of course is what drivers/char/mem.c:chr_dev_init() requires /calls for the i2c initialization. The patch worked via the module dependencies if CONFIG*=m, but fails if CONFIG*=y because char devices then try to load before i2c. This is very bad for char devices that depend upon i2c. In my case, this was seen while testing with OpenIPMI's ipmi_smb driver . We were also able to make this work ok with =y with lm_sensors 2.7.0 and prior. Corey Minyard from OpenIPMI mentioned that if the memset() of the drivers[] array were removed, it might work.
