Just reading through the whole thread to see if anything occurs to me.

A couple of things to check.

Did you try a different CPU than the one you hooked up to the serial port 
directly?  The CPU is 5V tolerant but I doubt it likes RS-232 levels very 
much.  That would damage the Rx line on the CPU (It might even appear to be 
intermittent).

Also you mentioned that you are pretty sure you got it into ISP mode 
because the program doesn't start (sounds like a good test).  Have you 
tried simply using a serial terminal to run through the first few steps of 
the communication when it is in that mode?  And compared it with the 
ashling board?
