Logic 7 works fine, and Logic 8 will startup in Core + TDM. It's only DTDM thats broken. I may just stick with 7 for awhile, although I have some downtime now, would be the perfect time to sort this out. I read some post on the LUG that says 10.4.9 is it for this combo, and I'm contemplating downgrading the OS, although I know its a PITA...
