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.

Got the same problem with my FX5200, panic with nvkush, gonna give it a try with 10.5.5 kext.
