suspend-to-disk: fan always on and misc kernel errors

Hello.

Long time after first trying suspend-to-disk, I gave it a spin again 
with 2.6.11.6, pristine save for two powernow/timer patches.

There are some rough corners, but it appears to be mostly working, 
including X. The glitches are:

1) scheduling while atomic (see kernel log)
2) script terminates with error and spews "command not found" problems 
only in the post-wakeup section, even though full pathnames are used 
(see script)
3) fan is always on, even though load approaches unity after a while

I'm attaching the suspend script I am using and the kernel log and I 
would like to hear from other people who have similar problems on a 
similar hardware: my laptop is an Acer 1357LMi, mobo chipset is VIA 
KM400 and vga is an ATI Mobility M9+. DSDT and other info available on 
request.

BR,
Andrea.
