Since I haven't seen (m)any reports about running Coreboot with a Core2Quad Mobile w/o microcode updates (The Libreboot docs even state that these CPUs are incompatible), I only wanted to report that for me it seems not to crash badly on booting or compiling. No more than that.

No problem, and thanks for the data point.  I just wanted to chime in so
that others are aware that on certain CPUs there are hidden risks to not
using update microcode; when making the decision to avoid microcode the
errata documentation for the specific processor in use needs to be
carefully analyzed for the intended use case to avoid an even less
secure setup than just using fully proprietary firmware.
