Can't build ds1621.o kernel module

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
So let me try this again. There are three things that would solve my
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.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Try to configure a kernel that yields a ds1621.o
This impacts lm_sensors, but I don't think it is a problem with that package.
Changing to kernel as component.
Read ya, Phil
Uhm this is supposed to be there
if not you can just grab the kernel from rawhide and use that... that has it for
