[root at gb0010 hotplug]# make
gcc -D__KERNEL__ -DMODULE -DLINUX -DM7101_DEBUG -O2 -Wall -I/usr/include -c m7101.c -o m7101.o
m7101.c:67:2: #error ERROR - You must have 'Support for hot-pluggable devices' enabled in your kernel (under 'general setup')!!
make: *** [m7101.o] Error 1

I'll try recompiling the kernel with hot-plug enabled...

[root at gb0010 sensors]# ./sensors-detect

This program will help you determine which I2C/SMBus modules you need to
load to use lm_sensors most effectively. You need to have i2c and
lm_sensors installed before running this program.
Also, you need to be `root', or at least have access to the /dev/i2c-*
files, for most things.
If you have patched your kernel and have some drivers built in, you can
safely answer NO if asked to load some modules. In this case, things may
seem a bit confusing, but they will still work.

 We can start with probing for (PCI) I2C or SMBus adapters.
 You do not need any special privileges for this.
 Do you want to probe now? (YES/no):
Probing for PCI bus adapters...
Sorry, no PCI bus adapters found.

 We will now try to load each adapter module in turn.
 Do you now want to be prompted for non-detectable adapters? (yes/NO):
 To continue, we need module `i2c-dev' to be loaded.
 If it is built-in into your kernel, you can safely skip this.
i2c-dev is already loaded.

 We are now going to do the adapter probings. Some adapters may hang halfway
 through; we can't really help that. Also, some chips will be double detected;
 we choose the one with the highest confidence value in that case.
 If you found that the adapter hung after probing a certain address, you can
 specify that address to remain unprobed. That often
 includes address 0x69 (clock chip).

Next adapter: ELV Parallel port adaptor (Bit-shift algorithm)
Do you want to scan it? (YES/no/selectively): no

 Some chips are also accessible through the ISA bus. ISA probes are
 typically a bit more dangerous, as we have to write to I/O ports to do
 this.  Do you want to scan the ISA bus? (YES/no):
Probing for `National Semiconductor LM78'
  Trying address 0x0290... Failed!
Probing for `National Semiconductor LM78-J'
  Trying address 0x0290... Failed!
Probing for `National Semiconductor LM79'

Probing for `IPMI BMC SMIC'

 Some Super I/O chips may also contain sensors. Super I/O probes are
 typically a bit more dangerous, as we have to write to I/O ports to do
 this.  Do you want to scan for Super I/O sensors? (YES/no):
Probing for `ITE 8702F Super IO Sensors'
  Failed! (0x5101)

 Sorry, no chips were detected.
 Either your sensors are not supported, or they are
 connected to an I2C bus adapter that we do not support.
 See doc/FAQ, doc/lm_sensors-FAQ.html, or
 http://www2.lm-sensors.nu/~lm78/cvs/lm_sensors2/doc/lm_sensors-FAQ.html
 (FAQ #4.24.3) for further information.
 If you find out what chips are on your board, see
 http://secure.netroedge.com/~lm78/newdrivers.html for driver status.

chmod +x and give it a try :)

i2c-dev is needed to probe I2C busses. Since you don't have any detected
yet, it doesn't change anything. But it will if the p4b_smbus module
works.
