0.4.6 r75446 on real Eee PC 701 4G, slipstreamed drivers don't install themselves

Hello, follows and "fixes" (CORE-13669) but seems a regression, my self compiled bootcd now completes all three install stages (phase one on Virtualbox and selecting VGA mode), XP slipstreamed drivers are in expected hard disk directories, but at the very end ROS doesn't load any real peripheal. No BSOD but also no joy. Thank in advance, if I can further help I will be glad.
