I seem to recall some kind of kernel problem with ACPI and fans not
turning on....I can't remember the details though, and I didn't have
this problem myself.

Now, why setting DynamicClocks in the xorg.conf file would turn your
fans on, I cannot possibly comprehend!!!

But, I'm glad it's working.

Interesting...maybe we should double check your ACPI configuration
options.  I have:

carcharias linux # grep ^CONFIG.*ACPI /usr/src/linux/.config
CONFIG_ACPI=y
CONFIG_ACPI_BOOT=y
CONFIG_ACPI_INTERPRETER=y
CONFIG_ACPI_SLEEP=y
CONFIG_ACPI_SLEEP_PROC_FS=y
CONFIG_ACPI_AC=y
CONFIG_ACPI_BATTERY=y
CONFIG_ACPI_BUTTON=y
CONFIG_ACPI_VIDEO=y
CONFIG_ACPI_FAN=y
CONFIG_ACPI_PROCESSOR=y
CONFIG_ACPI_THERMAL=y
CONFIG_ACPI_BLACKLIST_YEAR=0
CONFIG_ACPI_BUS=y
CONFIG_ACPI_EC=y
CONFIG_ACPI_POWER=y
CONFIG_ACPI_PCI=y
CONFIG_ACPI_SYSTEM=y

And during bootup, I get the following in /var/log/messages:

Jul 11 07:20:11 carcharias ACPI: AC Adapter [ADP0] (on-line)
Jul 11 07:20:11 carcharias ACPI: Battery Slot [BAT0] (battery present)
Jul 11 07:20:11 carcharias ACPI: Battery Slot [BAT1] (battery absent)

Jul 11 07:20:11 carcharias ACPI: Power Button (CM) [PWRB]
Jul 11 07:20:11 carcharias ACPI: Processor [CPU0] (supports 8 throttling
states)
Jul 11 07:20:11 carcharias ACPI: Processor [CPU1] (supports 8 throttling
states)
Jul 11 07:20:11 carcharias ACPI: Thermal Zone [THM0] (52 C)


Do you get anything similar?
