I suspected so. However the acpi and i2c section of the two config are
identical. I report the only selected options:

Power management options (ACPI, APM) --->
[*] Power Management support
[*] Software Suspend (Hibernation)
ACPI (Advanced Configuration and Power Interface) Support --->
[*] ACPI Support
[*] Sleep States
<M> Button
<M> Video
<M> Fan
<M> Processor
<M> Thermal Zone
(0) Disable ACPI for systems before Jan 1st this year

Device Drivers --->
I2C support --->
<M> I2C device interface
I2C Hardware Bus support --->
<M> VIA VT82C596/82C686/82xx and CX700

The first column of lsmod list the same modules in both kernels. The
diff-ed dmesg is attached.
