Well... after cleaning some points it booted stock. I put the chip back in there and it booted to evox. All I did was check to see if it booted, I haven't turned it on since. I am interested in catdog2's comment about the wire length. Something told me that they were a little long, but I was under a lot of pressure to get it out and it was like 2 in the morning. The solders really aren't a testament to my capabilities. I'm going to redo all the wiring with shorter wrapping wire tonight. That way it will react better to the 33mhz signals.
I'm still not sure why it went down in the first place (barring the bad solder). It might be that the length of the wires set up too much of a capacitance on the LFrame point, the overvoltage heated the LFrame junction inside the MCPX and shut the chip down. Or it could be something a lot simpler, like someone kicked the box at night (...and didn't tell me) which shook a shotty solder loose. I guess we may never know.
Is the way I did the mod correct though? Should I have left LFrame floating? I'd hate to see the same thing happen twice.
