It happens to me and I use the nvidia drivers at 1280x800 and 50 GHz.
If its fault of the propietary driver, i've had an idea to solve this.
Maybe we can run plymouth with the nouveau driver and later when plymouth ends running change the mouveau driver for the nvidia propietary driver.
The only problem is that I dont know how to make all this changes and make a patch.
