Initial texture parameters do not conforms to OpenGL ES 1.0 specification!   
Quote from OpenGL ES 1.0 specification:
"The initial value of GL_TEXTURE_MAG_FILTER is GL_LINEAR."

Software renderer conforms to this sentence, but hardware renderer which is provided by devg-extreme2 driver uses 
GL_NEAREST as initial value of GL_TEXTURE_MAG_FILTER, which is wrong.

Maybe GL_TEXTURE_MIN_FILTER parameter must be checked too.

Looks like problem is deeper than it appears: GL_TEXTURE_MIN_FILTER affect GL_TEXTURE_MAG_FILTER on devg-extreme2. 
Magnification filter became the same as minimization filter.

Ok, looking at the source, min_filter is initialized to be:

GL_NEAREST_MIPMAP_LINEAR

and mag_filter is:

GL_LINEAR

I seen you second response here, and maybe there is corruption in the driver, and an "off by 1" indexing issue ...
