It gets even worse.
I've got an implementation on my laptop which is quite buggy (it advertises 
itself as being OpenGL 2.03.. go figure). TexSubImage only fails after the 
texture you're trying to access has been used in rendering at least once.
This is an SiS on-board chip in a laptop BTW. My bug report seems to have 
been ignored completely :/
