I think that was probably me :)

I know this is a (not so) old thread, but where can I find the Kernel patches from 
2.6.29.5 to 2.6.30.4 for support with the 283667hg-A chipset in an asus 
P5q3-Deluxe? I can't really run 2.6.30.4 as it kills audio which I can't
 solve apparently, so I'd like to patch my 2.6.29 kernel directly.

By the way, my readings on the p5q3 when running 2.6.30.4 also can't be
correct:

I'm also more than willing to try whatever you want on this machine :)

This is all very confusing, I admit. I would like you to unload the
w83627ehf driver and try to read from / write to the chip directly. For
this you'll need the isadump and isaset tools (part of lm-sensors.)

Registers pwm1, pwm2 and pwm3 are at 0x01, 0x03 and 0x11, respectively.
You can see their raw value using the following command (as root):

isaset 0x295 0x296 0x4e 0 # set bank to 0
isadump 0x295 0x296

Then I would like you to write to each register, then check the result.
The value written doesn't matter as long as it is different from the
current value of all 3 registers in question:

isaset 0x295 0x296 0x01 0xaa
isadump 0x295 0x296

isaset 0x295 0x296 0x03 0xbb
isadump 0x295 0x296

isaset 0x295 0x296 0x11 0xcc
isadump 0x295 0x296

If this works fine then that would be a bug in the driver. If it
doesn't, that would be a hardware bug.
