I want to point out that there are other applications like
my Diamond (bug 2315, duplicate of 2320; Diamond is a crystal structure 
viewer), which are definitly also run on weaker hardware.
And at least a glxinfo |grep -i GL_EXT_frame does not return anything
on my Laptop ("IBM (ATI Radeon) RV250 Lf").
Maybe some solution which works on both high-end systems and on a bit 
older systems would be useful. (Implementing maybe conditionally 
GL_EXT_framebuffer_object and the work around?)
