KMS Custom EDID not working

Hi
I'm trying to get working my Dell E178WFP monitor at native resolution. It is connected through DVI-I - VGA adaptor, which don't forward EDID data, because my graphics card don't have D-Sub output. I have connected also second monitor through DVI-D connector, which send correct EDID data. My graphics card is Gigabyte GeForce GTX 750 Ti (DVI-I, DVI-D, 2xHDMI) using nvidia driver.
To fix that Dell monitor I downloaded EDID on another computer using read-edid and saved it on destination PC at /usr/lib/firmware/edid/dell.bin . Then in /etc/default/grub to GRUB_CMDLINE_LINUX_DEFAULT I added drm_kms_helper.edid_firmware=edid/dell.bin and did grub-mkconfig -o /boot/grub/grub.cfg. After restarting there was no effect. /var/log/Xorg.0.log
So my question is: What's wrong and how to fix it? Thanks in advance.
(sorry for my engrish)

EDIT:
Solved it not way I wanted to, so question is still open. I got BadMatch error when I was trying to add custom resolution to monitor like here and found solution to this here. Not solved, here. But I still want to do that EDID way because I plan to install Plymouth and I want to be able to use TTY at native resolution.
