Ok, here some more input from my side:
I updated to the latest 7-stable, which identifies as 7.1-prerelease.
Booting default still locks up after launching the additional cores.
Booting without acpi behaves a bit different from before: It finds the
onboard sata-controller, but does not find the hd anymore. Thus it breaks
into the "Manual root filesystem specification" menu (but there is
nothing to specifiy as the disc is not found at all). The same happens when
I set hint.apic.0.disabled="1" at the loader prompt.

If someone can tell me what to do (except for putting ddb into the kernel
configuration) or point me at some documentation about this, I can try
getting some useful information from the debugger.
