We struggled with this for a while. For example, we tried not only multiple versions of Thunderbolt firmware but different modifications on each version. I'll add an appropriate notice in the Thunderbolt Repository.
Although everyone is experiencing the warm-boot issue on add-in-cards only (not on built-on controllers) I don't think everyone is experiencing those kernel panics.
You're welcome to try, but we were not able to solve the warm-boot issue with any of these.
The modified DROMs are based on the original DROM that accompanied each device. The modified GC-Alpine Ridge DROM is therefore based on the original GC-Alpine Ridge DROM.
If your motherboard has a Thunderbolt header (THB_C) then it's highly advisable to use it -- or at least to experiment with it. Such motherboards also provide Thunderbolt configuration parameters in BIOS, and those parameters should be configured properly. If in doubt about those parameters, simply post screenshot(s).
If your motherboard has a DisplayPort output on the rear IO panel, then try connecting that to one of the DP-INs on the GC-Alpine Ridge. Platform ID should be 0x3E9B0007, which I suspect it is already because you're already relying on internal graphics.
Regarding the warm-boot issue, are those having this problem putting a the jumper wire from pins 1 to 3? That was mentioned as being necessary to get it to boot in this video, and also one of the people selling the pre-flashed cards on ebay mentions including a jumper cable.
