lm-sensors and lm78 chip

[Andrew Perrin <clists@perrin.socsci.unc.edu>]

Greetings-

I'm trying to get lm-sensors to work, mainly to monitor the CPU
temperature in my machine.  I know the chip is an lm78, as reported by the
following output from sensors-detect:

Probing for `National Semiconductor LM78'
  Trying address 0x0290... Success!
    (confidence 7, driver `lm78')
Probing for `National Semiconductor LM78-J'
  Trying address 0x0290... Failed!
Probing for `National Semiconductor LM79'
  Trying address 0x0290... Failed!
Probing for `Winbond W83781D'
  Trying address 0x0290... Failed!
Probing for `Winbond W83782D'
  Trying address 0x0290... Failed!
Probing for `Winbond W83627HF'
  Trying address 0x0290... Failed!
Probing for `Winbond W83697HF'
  Trying address 0x0290... Failed!
Probing for `Silicon Integrated Systems SIS5595'
  Trying general detect... Failed!
Probing for `VIA Technologies VT 82C686 Integrated Sensors'
  Trying general detect... Failed!
Probing for `ITE IT8705F / IT8712F / SiS 950'
  Trying address 0x0290... Success!
    (confidence 7, driver `it87')


But trying to load the modules turns out to be impossible:
joehill:~# modprobe i2c-isa
modprobe: Can't locate module i2c-isa
joehill:~# modprobe lm78
modprobe: Can't locate module lm78


And sensors doesn't see anything:
joehill:~# sensors
No sensors found!


How do I get this working?  I did select I2C support in the kernel (as
modules), and have them loaded:
joehill:~# lsmod
