Boot FX/5XXX cards on 10.5.6 w/acceleration

I've been doing some testing lately (and still am) and I noticed a couple of things.

I have a FX5500 128MB AGP card installed on this machine, and it's supported with NVinject, NVKush and NVdarwin on 10.5.5 and lower.

However, upon updating to 10.5.6, I noticed that I could not boot, and it was always after those injectors did their probing. When I removed them, I could then boot, without acceleration.

This was tested on another HD, so I booted into my 10.5.5 system, and copied the old nvidia kexts I installed when I updated to 10.5.5 and moved them into the 10.5.6 system and it booted.

Now, I noticed that many people with 6XXX cards or higher can boot fine after updating. So this must be a <6XXX card issue.

If you have an FX5200 card or higher, but not a 6XXX card, I suggest trying the kexts from 10.5.5 if you can't boot after updating to 10.5.6. Make sure it's the injector at fault by booting with -v and watch when the injector does it's magic. It should hang shortly after.

Please let me know if this fixes your boot problems.
