After several google searches and reading up on posts by others abt
similar problems with ACPI,  I was leaning towards the theory that it's
got something to do with the Intel 855 graphics adapter on both my
Fujitsu and Mads's ASUS. I read on another post that the graphics
card had issues with ACPI (that one wasn't Intel 855)..

But after looking at the syslog, this doesn't seem to be the 
problem: there was a message that said it was
looking for "Module char-major-10-134" (the APM module) when it 
resumed -- I put in an
alias to set this to off and that error went away. I also removed
all the modules before I suspended and that reduced the number of
errors I get when it resumes. But these are the remaining messages
from syslog:

So looks like there's some problem with the uhci-hcd controller? I 
googled and it's a recognized bug:

http://bugzilla.kernel.org/show_bug.cgi?id=1373

The workaround suggested is to rmmod the uhci-hcd module .. I have 
it built into the kernel so maybe I need to recompile this as a 
module... However, the others have been able to resume, just that 
the USB devices don't work.. mine doesn't resume at all.. could this 
have to do with the following error above:

cpufreq: resume failed in ->setpolicy/target step on CPU 0

Should I uncheck the CONFIG_X86_ACPI_CPUFREQ=y option in the kernel 
config?

Btw, the thermal_zone directory in /proc/acpi is empty.. I did 
enable it in
the kernel configure .. the same goes for fan/ - it's also empty. Do
these work for you?
