No, Alphas are little endian, just like x86. The major difference is
that they're 64 bit.

PPC is big endian like SPARC, and Q2MAX is working perfectly here
AFAICT.

If gl_ext_multitexture is enabled in the Q2 configuration, the OpenGL
implementation might handle the lightmaps inefficiently (a common
issue).
