there are several ways to get a pure console.
1. is to use emergency mode.
2. meanie says that if you run his pdaxii13 install files, you can select a console from within the installer.
You don't have to install anything, just follow instructions as if you want to install pdaxii13, then choose terminal or console. there is a selection for it on the installer menu.
EDIT: look on meanie's page for fsck
This is where he explains several ways to get to a console. (so you can run fsck without the HDD being mounted)
EDIT2: If I recall correctly, doesn't the pdaxrom beta3 installer have an option to open a console? (similar to the pdaxii13 installer)
