cpufreq active? This has not much to do with ACPI, though.

Probably not a general ACPI problem. Read Documentation/power/video.txt

sony crap bios, no ACPI fan control methods => not an ACPI problem

you need Stelian Pop's sony_acpi module for that (and a mechanism to adjust
the brightness on ac adapter plug/unplug, powersaved does this on SUSE).
It might also work with the generic_hotkey module, but i could not figure
out how to do it (i remember posts on acpi-devel that claimed that all
vendor specific acpi drivers are obsoleted by generic_hotkey, still have
to find out how to control the brightness of my panasonic with it).

SONY crap. These are no ACPI hotkeys, all the hotkeys on the vgn-fs115
emitted a standard keycode. Unfortunately all emitted the same keycode.
SONY notebooks are just badly designed IMO, even the Windows XP drivers
and utilities looked and felt very hackish.
Although the hardware / case / display / keyboard were fine, i would
probably not buy a SONY if i had to pay it with my own money.

Most of the problems you have are probably not ACPI problems.
