From testing in #blitzbasic and #blitzcoder, it's looking as though nVidias can't handle the 256 flag, ATIs can handle either, and certain Intel chipsets are the ones that require 256.
Thinking I may need to do a quick initialization call that creates two small textures, one with flag 1 and one with flag 256, plot a point to both and then test that point to see which flags 'work'. Ugly but doable.
