Ok - I found the bad trace - it was
UNDER the right hand side chip. Repaired the trace and refitted the existing ram. There is continuity now across the pin that was lifted, and looks like no broken traces.
Here was the problem
And under the microscope
Now I have a new problem, The Diag Bios is completely unusable after refitting the ram, and when I use the Universe Bios, the screen is a lot more illegible too. I need to get pics.

What I see in Diag with a cart. If bridge some pins on the Ram with a logic tester, it gets a bit more legible, but still cant read anything.
Oh also - here is the repair of the pad with Kynar wire. I tested it and its got good continuity up to the pin and isn't bridged.
Darn.
