ATI Mobility Radeon problems (OpenGL)

So, I'm making this opensource didactic examples to help a teacher to show CG tecniques with interactive examples. Two of them are related to cube-mapping and another one has a phong shader. I'm having problems. 

I've made the samples on my desktop with a NVidia 9800 GTX+ and tried them on my laptop which is a HP DV-4 with a HD 4200 Mobility Radeon card, two problems arised, first, texture border does not work on the HD4200, no erros, just freezes, also, when I'm using shaders, I get a error linking the shaders, if I ignore it, the shader still runs perfectly even tho GL_LINK_STATUS returns 0 (both problems do not happen on my desktop). Also, no infolog is returned after I link the shaders

I can live with both problems but I want to make it right, first, is there any way to check if texture border is availible? as far as I know there's not texture border extension (to be checked) and it should be part of usual OpenGL implementation (1.3 if I'm not mistaken)

I've looked alot for a way to check, updated drivers and still got nothing. Any ideas? Thanks alot!
