I've never looked too much into this, but so far I've used LPM_ROM with HEX memory initialization files and both Quartus and ModelSim managed to load the memory contents correctly.

I've never actually tried using the MIF format and I don't know if it's even supposed to work or not.

But it may be that you're using the LPM_ROM component from ModelSim's libraries instread of from Altera's Libraries.
