HD 3000 is supported after you install and after you do a few things. It isn't supported in the installer. And we really don't know which graphics card is shutting you down - the 7470 or the 3000. You don't really need any drivers to perform the installation, so I would do two things:


1. Try booting: -v -x cpus=1 busratio=22 PCIRootUID=1 GraphicsEnabler=no


If that fails,


2. Go to the Lion installer in /System/Library/Extensions and remove all AppleIntelHD* files, AppleIntelSNB* files and ATI* files. This means you have no drivers for either of your cards. But each card contains primitive drivers called VESA drivers. They will give you enough graphical support to proceed with the installation.
