problem at the welcome screen (after touching yellow circle to proceed)

[Key Cut]

Hey guys, I'm trying to run Android-x86 on my TERRA PAD 1061 by Wortmann.
You can find the specs under details here: http://www.wortmann.de/en-GB/product/aa_terra_pad_pad/1220449/pad.aspx

I tried the live mode of the Android-x86 6.0-rc2 live and installation iso (32-bit). To see something after grub boots up I have to add 'nomodeset' to the boot options like described here: http://www.android-x86.org/documents/how-to-boot-the-android-x86-live-cd-when-you-have-problems-with-your-graphiccard
The silver android loading writing appears and some time later the android welcome screen (blue background, welcome text, language selection, emergency call). There I can select other languages and even open up the emergency call screen. But as soon as I touch the yellow circle with the arrow inside to continue the android writing appears again as if it crashed and tries to restart. It’s not a reboot, because grub is never shown and it almost happens instantly. Then some seconds later the welcome screen appears again and the whole circle starts again.
This crash also happens automatically without touching the yellow circle after the welcome screen is shown for about one minute.
Debian 8.5 works almost fine (here I also have to use nomodeset), does somebody know why I can’t get past the welcome screen of Android-x86?

Here are some logs:
Logcat: (I had to split the logfile, because it was too big for Pastebin)

Thanks for your help!

Your device uses software rendering (non-GPU accelerated)
with resolution 1920x1200. I guess the mode is not stable.
The most stable resolution of software rendering
is 1024x768. You may try to add this to kernel cmdline:

video=efifb:width:1024,height:768

Alternatively, you can try if newer kernel
supports (fixes) i915 native fb driver on your device.
There are several testing isos posted in this group
with kernel 4.8-rcX that you can try.
(don't add nomodeset and see if i915 loaded correctly)

That’s it! You are right!
By adding video=efifb:width:1024,height:768 to the kernel cmdline I really can proceed to the wifi selection screen. Thank you for enlightening me!
Now only the left top corner of the screen is used but the touchscreen uses the whole screen. This is weird and makes it unusable.
I'll try to find an image with a newer kernel and test that.
