I'm reopening this, as I'm still seeing link train fail, and cannot use both monitors at 2048x1152 with IVB yet. I'm seeing this with the kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.8-rc2-raring/ which appears to include your changes from the intel-fixes branch, per the CHANGES file in that directory.

I can however, now use the second screen at 1360x768 (1366x768 or higher fails), even with the primary screen at 2048x1152, now. Of course, there are still link train failure messages in dmesg:
