There must be a pretty basic problem remaining because the driver fails after a few seconds. Win7 reports that a kernel mode thread has spent too long in the ATI driver code.
I guess that the watchdog is those few seconds. Does graphics work during that time?
Could you use windbg to get more details, in particular find out what the ATI driver was trying to do?
A few shots in the dark, maybe they help. Is it possible that the failure reason is totally unrelated to graphics? Maybe the ATI driver uses a timer which is set up differently under coreboot? Or it is waiting for an hardcoded interrupt or some ACPI event which only exists in the reference BIOS? Side note: RS690 ACPI PCI config space accesses were broken in coreboot because they assumed MMCONF and MMCONF was disabled before starting the payload last time I checked. Maybe your issue is related?
