it looks like there might be a way to run ati x1400 with evoenabler and ati1600controller.kext. edited ati1600controller, atix1000 and atiframebuffer kexts with proper ids, installed with evoenabler. the problem was there was no output on lvds, but the laptop was loading. i had ioregistry loaded on startup so i managed to save the info blindly. i include the saved file. what i think for lvds no output the problem might be mac not reading EDID from lvds. i tried to force to read it by editing info in system/library/displays but no output. it might be that my EDID was wrong, though it works well with RadeonHD.kext. i extracted it with ubuntu.
if anyone is willing to work on this i can give more info on how i did this.
does anyone know how evoenabler works. is it using atiframebuffer.kext or does it use it's own framebuffer. i'm doing this all to make the card work with ati custom personalities.
Acer Aspire 5672WLMi, ati x1400 128Mb,
You can try value "@0,override-no-connect". It works for me.
I haven't managed to find any other way to get working video with ATI1600Controller.kext.
Only with "@0,override-no-connect" driver gets correct EDID.
See attached file: EVOEnabler.kext\Contents\Info.plist.
PS: Have you tried sleep and wake? With ATI1600Controller my laptop can't wake - reboot. The reason - a kernel panic.
