I have an ASUS A7V333 which definitely has the ASB100 chip (on $2d: $58=31, $4f=06), not to be confused with as99127f or the w83781d, although some functionalities are the same. Your NEW AND REQUESTED CHIP DRIVERS - STATUS states that the asb100(bach) is recognized as an as99127f. The as99127f and the asb100(bach) have different ID's and behave differently because using w83781d force_as99127f is not working I downloaded xmbmon from: http://www.nt.phys.kyushu-u.ac.jp/shimizu/download/download.html Also the link to FVCool, for anyone who wants to drop the CPU temp by about 23 - 24 F in under 5 minutes. Mbmon gives me numbers very consistent with CMOS Hardware Monitor, BUT it is either command line or Ugly X, and the docs contain a warning that it is probing the chips directly. This can cause problems and make the system unstable. From the command line, mbmon -f, I even get the power fan2 rpm = CMOS rpm, which I do not get with xmbmon, nor have ever gotten from sensors. If I modprobe the i2c and lm_sensors modules, mbmon and xmbmon start giving me crazy numbers (for example CPU =145.1 F, up from 90.5 a few moments before), as does sensors. The only way to restore sensible numbers again is to reboot. How Come? I was going to try to hack w83781d.c into something useable, but alas I am too dumb. I offer what I know about this chip in hopes one of you can do it, maybe as a force_asb100=0,0x2d option to w83781d.
