Acer Travelmate 4651lci: freeze 10-20s after resume (S3)

Hi, 
I try to configure suspend to ram on my new Acer TravelMate 4651lci. I added 
the option acpi_sleep=s3_bios to my boot loader. 

I can correctly suspend the laptop (echo -n mem > /sys/power/state). When I 
enter a key the laptop resumes also. Unfortunately the laptop freezes 
approximately 20 seconds later. The system doesn't react any more. I also do 
not get any error message on the screen. 

I uploaded lspci, dmidecode, acpidmp and lspci -vv and interrupts to my 
website: 
http://bram.be/lspci.txt 
http://bram.be/dmidecode.txt 
http://bram.be/acpidump.txt 
http://bram.be/interrupts.txt 

I tried it with several kernels (ubuntu 2.6.10 and the latest
2.6.12.3<http://2.6.12.3>(with and without acpi patch)). They all give
the same result.

Any ideas on how to fix this? 

Thanks, 
Bram.

Does it freeze without s3_bios option? Does it freeze in kernel or in
userspace?
