Native custom chipset modeIDs are now correct. (special modes like EHB or HAM not available yet)
RTG driver does not override custom chipset driver anymore. RTG still has "mode promotion" enabled, boot menu and boot shell use RTG if available.
Custom chipset modes open "behind" RTG mode at the moment. AROS thinks RTG and chipset modes are using different separate monitors, mode switching needs to be implemented. (which means it is difficult to see any custom chipset screens if RTG is enabled..)
