Still no luck, still hangs at boot.

You can find acpidump and dmesg at:

http://62.196.71.254/kernel/acpidump.gz
http://62.196.71.254/kernel/dmesg.txt.gz

I noticed that booting with serial console enabled succeeds also with 
failing kernels;
I've to do more testing to see if it's a 100% success ratio.

dmesg is relative to vanilla current git kernel, booted without docking 
station and with serial
console enabled. Inside it you can find some acpi related error; I don't 
know if they're relevant.

Kind regards
