I'll try this tonight when I'm back at home. The laptop concerned uses the ICH-7M part in "legacy mode" so it doesn't do AHCI at all :-(

Without sdhci and mmc, it actually boots but everything KDE aborts with signal 6 :-(

I'm not prepared to rebuild the ~1900 ports on this box to pursue this further,

Something about SVN r320844 causes almost all KDE applications to fail on a signal 6.

I've recompiled KDE and other components obviously dependent on kernel structures (e.g. everything dbus-related). I still get core-files with a back-trace that looks like:

SVN r320843 works, r320844 doesn't :-(
