Can't boot without removing NVDA* after install

[rkn]

Hey,

So previously the only way for me not to get a flickering/black/useless screen after booting up has been to boot up with -s and "rm -rf NVDA*"-files from Extensions/, but I realize this cripples my graphics, so my question is: is this a usual problem, and how do I solve it?

I'm using iDeneb_v1.6_1058_Lite_Edition, no selected nvidia drivers, just default.

My theory is, that I need to select some kexts like nvdarwin and then use a EFI-string after booting and then remove nvdarwin, because NVDANV40/50HAL.kexts can't figure out my gfx elsewise?

Thanks

Adding NVDarwin simply made the screen go black, instead of constant text flickering.
Edit: "simply" by removing NVDAResman.kext, it would boot, adding it again causes black screen. WHY
