So plymouth under most situations won't resize the display.  It just
uses what the kernel dishes out.
It sounds like you may be having some sort of driver issue.

Do make sure you don't have vga=0x318 or some such on the kernel
command line forcing a vesa mode.

Ah, I see, so definitely a kms issue.  Maybe you can workaround it by
disabling the output on the kernel command line?
