In this line I have libsysfs.so.1. Is this a problem?

I have read that one, but I don't see how it can help me.

So far I think I have it. By the way, the directory for the w83627ehf.c 
driver is /usr/src/linux/drivers/hwmon. Might be a special SUSE feature.

Okay, I skip this and try the rest first.

This seems all okay.

After menuconfig I was prompted to build the new kernel by issuing make. 
When I do this everything works fine until make comes to the new 
w83627ehf.c file. From then I only get errors and make stops proceeding 
(takes about 15 seconds).
I then copied the old w83627ehf.c file back and tried make again. It 
took about 10 minutes and complained a few times but the driver 
apparently was built correctly.
I changed again to the new w83627ehf.c file in order to have a closer 
look at the error messages. I issued make cloneconfig, make menuconfig, 
make. It all worked. I don't know what was different this second time. 
It took about 30 seconds and the only thing that was recompiled was the 
w83627ehf driver.
I got these messages:
...
Building modules, stage 2.
MODPOST
CC                 drivers/hwmon/w83627ehf.mod.o
LD [M]           drivers/hwmon/w83627ehf.ko

What do I have to do now to load the new module? (modprobe -r w83627ehf 
and then modprobe w83627ehf does not work: no such device)
I think I have  recompiled only a module so I do not need to change the 
whole kernel. Is this correct?

Thank you for your support. I'm optimistic that we will be getting 
sensors to work.
