After looking, I noticed that it rolled back to defaults and not to 10.5.4. It actually left the 10.5.5 in place but reset all of the system defaults. My system booted right after I did that and it's working nicely now. Thanks for responding though and if anyone else gets stuck, here's what I did:

boot in safe mode
open OSx86 tools
hit the Restore OS X to Defaults button (you will lose files etc.)
and then restart

it worked
