      linux driver reports differ from spec

      I recently purchased an ATI Radeon HD 5770 GPU. On AMD's website the specs page says that it is supposed to have 40 Texture units. But when I perform the following query in my opengl application:

      glGetIntegerv( GL_MAX_TEXTURE_UNITS, &maxtextureunits);

      it returns 8 texture units.

      Is this an issue with the OpenGL driver on Linux, or have I simply misunderstood the specification? Unfortunately I don't have a windows operating system to compare the results with.

      I'm using the Catalyst-9.12 driver, my kernel version is linux-2.6.31,
      my processor architecture is amd64, and my linux distribution is gentoo.

      Best regards, frax
