It seems like >GfxBase->DisplayFlags does not reflect this. Another way to do it is to check the PowerSupplyFrequency and VBlankFrequency fields of the ExecBase structure (i think they're called that). If they're 50Hz, you're PAL, if they're 60Hz, you're NTSC. If one is 50 and one is 60, then you have an NTSC sized screen on a PAL system (this bug under 1.3 and less occurs every so often).
