I havnt any kernel specific related issues since version 3. I do not have a sse2 only machine.Most programs run without std_dyld=Yes although I can only run 3d accelerated games that use a wine like engine with that boot string included. Hope that helps. I have a geforce 310 - m4a785-m - amd athlon II regor 240 - kingston hyperx ddr2 800mhz
