200Â though, possibly the kernel should set a default upper limit, unless there's
a rational reason

I'm tending to a similar conclusion, it looks as though that's generally the case
with many Aspires; there is a script for poking the hardware registers
http://code.google.com/p/aceracpi/source/browse/trunk/acer_ec/acer_ec.pl referred
to at http://www.linuxquestions.org/questions/showthread.php?p=4657451 though it
sounds a somewhat risky/random business without the manufacturers' specifications
at the ready

there are 2-3 symbols in the ACPI that may be relevant, FANG, FANW, possibly
FANU; I attach the relevant files

thanks for helping me :)

Best regards

Mark
