Bug 73631

Description of problem:
I am working with the latest kernel from RH which is 2.4.18-10.

I want to get lm_sensors working and it tells me that I need to have 
ds1621.o available as a module.  For the life of me, I can't figure out 
what entry in .config to access to affect the creation of this object 
module. It might have something to do with drivers/char/ds1620.c or it 
might be drivers/sensors/sensors.c I really can't tell. And there's 
nothing intuitive to see in the .config file. I spoke to a guru friend of 
mine who is running Mandrake who actually has a CONFIG_SENSORS_DS1621=m in 
*his* .config while I do not.

So here's my question:

1. Is this a bug? i.e., is the src code provided but there's no access to 
the object via the standard config interface?

2. Can someone please tell me what the exact compilation command is to get 
this object module?
I did sensors-detect and it told me what modules I need to modprobe. One 
of the modules it told me I need to modprobe is ds1621.o and it's not 
there. The kernel supplied by Red Hat does not come with ds1621.o and I 
can not find out how to build it; there is no option in the kernel .config 
file to enable the production of that module. I do have lm_sensors 
installed and it seems to be working. But I am not getting access to one 
of the sensors and this is the missing module. And, yes, I do have the 
lm_sensors installed that comes with the distro and that is at rev 2.6.1-1

I suspect that there is a bug because of what I said about my Mandrake 
friend: He can create the module and I can't. He has a CONFIG_DS1621=m in 
his .config and I don't. (I did try to add it manually but it gets 
ignored.)

So let me try this again. There are three things that would solve my 
problem:

1. Someone could send me ds1621.o
2. Tell me what config option I need to set in the kernel .config file to 
   cause this module to be created.
3. Confirm that I have indeed discovered a bug in the kernel which 
   prevents this option from being available.

Additional info:

This impacts lm_sensors, but I don't think it is a problem with  that package.
