spice-gtk doesn't use GPU acceleration directly, it uses pixman, which doesn't use that either. pixman does make use of NEON and, SIMD, IWMMXT and IWMMXT2 instructions on arm - this is just copied from ./configure --help of pixman's tip, no idea which of these are packaged.

If it turns out this is not enough on your cpu you will have some work cut out for you. I know there is at least one intel project that does 2d rendering via OpenGL or maybe GLES (glamour I think).
