Hello,

Symptoms: modprobe i2c-core works fine but /proc/bus/i2c doesn't exist

Kernel : Stock 2.6.0-test5-mm2
Distro : Debian Sid + 2.8 lm-sensors user space utilities
Hardware: Dell WS 530MT SMP Xeon 1.5 Ghz, Intel Motherboard Chipset: 82801BA , ADM1023
00:1f.3 SMBus: Intel Corp. 82801BA/BAM SMBus (rev 04)

Also while rmmoding i2c-dev module, i got the following message:

Device class 'i2c-0' does not have a release() function, it is broken and must be fixed.
Badness in class_dev_release at drivers/base/class.c:200
