Wow, there's some really interesting stuff in your DSDT. It seems that the
nice people from ASUS decided to make their users' (and my) life easier, by
implementing frequency control methods for their driver. Since I'm leaving
in a couple of days, this won't probably be implemented for some time yet
(unless Julien gets to work on it), but look forward to getting basic
support for your laptop in the tomorrow's acpi4asus CVS.

I'll keep track of it. I have some updates. After turning the portable
off last night, I turned it on this morning, and the problem seemed to
have disappeared... the process was not eating cpu anymore. I started
X, and the fan started working briefly, then stopped when I left X. I
did a reboot, and things were still OK. Then, when I started a 'make
menuconfig,' the fan started working again, and exactly then the
process began again to eat 99.9% of the CPU timæ.

The problem is really connected with fan operation: if I go look at
/proc/acpi/fan/FN00/status, I find

status:       off

while the fan is instead very much in operation. If I do

echo 'on' > state

the content changes to 

status:       on

but if I then try to write 'off', mothing changes. Can this all be
useful for tracking down the problem? 

BTW: Have you tried recompiling your DSDT? The MXN DSDT's oddly contain
some trivial-to-fix errors (like the If(SSn) statements in your case),
there's even an updated DSDT at http://acpi.sf.net.

I read something (and I am under deadline for my work... grgrgr) about
all this, but I could not learn enough to be confident with the
process. 

Maybe later...

Thanks in all cases

Carlo
