plymouth does not recognize resolution

[empax]

I am trying to change the splash screen resolution by using this[1] BASH script which uses uvesafb kernel module, but it does not take any effect. Nvidia propriety driver is being used for VGA device.

Steps to produce problem:
1- Install nvidia propriety driver
3- Install v86d package
3- Use the script and change resolution
4- Reboot
