FYI, the system itself appears to be running OK...keyboard is responding to numlock, I can ping, etc., it's just the display that's in an invalid mode.
Let me know what else I can do to help debug.

Next log with debug tracing added to i2c.c's spin() implementation to ensure gcc4 wasn't optimizing it out somehow,

Based on banging on things all weekend, I think it's possible we might be looking at the wrong problem...one of the recent changes in the tree caused whatever mode EDID detected during boot to be written to the app_server_settings file immediately to prevent a mode switch, which in turn short circuits the radeon's monitor detection routines...however, I still end up with the same invalid signal to the monitor. At this point I'm starting to think something's going wrong with the kernel driver's setup of things, since I also tried forcing the routines that query the BIOS for the connector types to force DVI, and that also made no difference.

It must be an i2c issue IMHO. it works in GCC2 and fails in gcc4.
