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 R
