You need the core i2c modules loaded.
$ lsmod

Subject: /proc/bus/i2c is missing
Hello
linux 2.6.8.1
I insmoded i2c-parport and pcf8591 modules and i2c-1 appeared in my /dev
(previously, only i2c-0 was there):
clock@oberon:~$ ls /dev/i2*
/dev/i2c-0 /dev/i2c-1
/dev/i2c:
0 1
/usr/src/linux/Documentation/i2c says "You can
examine /proc/bus/i2c to see what number corresponds to which adapter."
I don't have any /proc/i2c:
clock@oberon:~$ ls /proc/i2c
ls: /proc/i2c: No such file or directory
However, I have /proc:
clock@oberon:~$ ls /proc
devices mtrr
diskstats net
dma partitions
driver pci
execdomains scsi
filesystems self
fs slabinfo
ide stat
interrupts swaps
[...] iomem sys
ioports sysrq-trigger
irq sysvipc
kallsyms tty
kcore uptime
kmsg version
loadavg vmstat
locks
buddyinfo mdstat
bus meminfo
cmdline misc
config.gz modules
cpuinfo mounts
How can I make /proc/i2c appear?
