Tried it on My MacBook Pro, got that it has GL_ARB_texture_non_power_of_two. According to the log file that I got while debugging on iMac / GeForce 7300GT, it supports GL_ARB_texture_non_power_of_two as well. I also tested A6M2 with resized panel.rgb (500x500) and it worked properly. The log file showed: Scaling image '<snip>/data/Aircraft/A6M2/Models/panel.rgb' from (500,500) to (512,512). Now I can tell that OSG properly rescales the image on Mac OS X (at least on my MacBook Pro with ATI Radeon X1600).
