Do you mean reprogramming CRTC registers? I remember that it was primary used for setting higher refresh rates in CRT age but nvidia dropped this VBE code since GeForce 5xxx and newer. I remember that intel 945 has it. I used it to set 85Hz on my CRT. But never tried to completly modify it for different resolution, maybe it is possible. The 288x224 that MAME does is probably usefull only for CRTs, I suspect that LCD would sync on it.
I'm also afraid of 16:9 noodle displays, I don't know if still available some new better 4:3, my NEC 2190UXp was disappeared from shops...
