i2ctools in lm_sensors

NB: This is really a continuation from i2c drivers, but more on the application side. Hippo, I tried to include lm_sensors (which includes i2ctools) in menuconfig, but it got error. P...

Hippo,

When I built the driver into the kernel, and boot up the system, I get the following 

Uncompressing Linux... Ok, booting the kernel.
Linux version 2.6.Uncompressing Linux... Ok, booting the kernel.

Does it mean the drivers are in ?

Also, when I try to do i2cdetect, I get this. 

/nios2bin> ./i2cdetect
Error: No i2c-bus specified!
Syntax: i2cdetect   I2CBUS 
  I2CBUS is an integer
  With -f, scans all addresses (NOT RECOMMENDED)
  With -q, uses only quick write commands for probing (NOT RECOMMENDED)
  With -r, uses only read byte commands for probing (NOT RECOMMENDED)
  If provided, FIRST and LAST limit the probing range.
  i2cdetect -l lists installed busses only
  Installed I2C busses:
    i2c-0       unknown         Opencores i2c 0                         Algorithm unavailable
/nios2bin>

It looks like the algorithm is NOT available.

but, when I try modprobe i2c-algo-oc, I get the following 

/nios2bin> modprobe i2c-algo-oc
modprobe: could not parse modules.dep

This is very confusing for me. Please help.
