That is an expected result. 256MB is not enough for the VRAM BAR and the
doorbell BAR to fit into. But you can still use VGA emulation that way
if I'm not completely mistaken.

How did you do this? Is your memory layout consistent?
See when you just changed one end address you might need to adjust other
addresses as well.

Christian.
