I think you both may be missing some important details about ACPI. Just because
Xandros' control panel mentions ACPI doesn't mean that they actually have a full
ACPI implementation. ACPI is very much in a state of flux and you need special
patches from sourceforge for 2.4 kernels - I very much doubt Xandros is
up-to-date. You don't have ACPI fan control unless you have /proc/acpi/fan and
/proc/acpi/thermal. The default ACPI implementation in 2.4 can essentially turn
off your laptop cleanly when you push the power button.
In Jaye's case, it probably doesn't mean it reads the temp incorrectly - just
that it has no thermal trippoints defined in ACPI. My Dell doesn't either, but
hardware controls the fan so I don't have to worry. In both your cases, I
expect you need to recompile the kernel with the appropriate patches.
