"ACPI compliance" is somewhat of an academic concept,
as there exists no industry standard platform compliance test suite...
It is still possible to compile a custom DSDT into a build-from-source kernel
by following "How to Build a custom DSDT into the kernel" here:
http://lesswatts.org/projects/acpi/overridingDSDT.php
However, DSDT overrides are for debugging, rather than for supported systems,
as nobody except the owner of the DSDT code (the OEM) can support
the modified firmware.
Generally if the system is functional enough to work with Window's
ACPI implementation, we will make it work with Linux's ACPI implementation --
even if it means adding workarounds for brain-damaged systems.
However, we stop short of adding features that that the OEM
failed to implement.
It may be that you want to be looking into the compal-laptop driver
for help in supporting features that are not implemented via
standard ACPI methods. I would not worry about thermal and fan --
they're probably handled by an EC, like they are on most systems.
Wireless (and rfkill) is not a feature standardized by ACPI.
LCD brightness is standardized by ACPI, do you have anything
in /proc/acpi/video or /sys/class/backlight?
