Do you mean the PGRAPH errors in dmesg? Any other errors displayed to the console or other logs?

Your report is a bit ambiguous on one point: You say you've been seeing the bug "since Quantal, around Beta2", however you later say that "Booting back on the current Quantal kernel" restores it to working. Care to clarify? By chance could you be lumping two distinct bugs together?

Focusing on the raring 100% failure on login. There are mainline kernels at http://kernel.ubuntu.com/~kernel-ppa/mainline/ you can try testing. If it were me, I'd start at 3.5-quantal and verify that works, then test v3.7-rc6-raring and verify that fails, then randomly test kernels between those versions to narrow down when the regression first starts.
