Yes, it should be easy to adapt to lm-sensors, all you need to do is
move the code to a Linux kernel driver and add sysfs attributes to
export the temperature to users-space.
The fact that this is a PCI device isn't a problem at all, we already
have several hwmon drivers for PCI devices: k8temp, sis5595, via686a,
vt8231 and, I believe, i5k_amb.

A couple notes:
* You make use of PCI_FILL_CLASS while as far as I can tell you don't
need it. This prevents your tool from building with older pci header
files so you may want to stop using it.
* On my laptop with an ICH7, the tool reports "Your GPU temperature is
under 40 degrees Centigrade". This laptop has an ATI Radeon graphics
chip so the Intel IGP isn't used. So I am curious if the value returned
by your tool is meaningful or not?
* Note that the correct unit name is degree Celsius, not degree
