A quick search for GPU OCR turned up tons of articles, the not much in the
way of off-the-shelf implementations.

The buzzwords you're looking for are GPGPU (general purpose GPU) and "GPU
compute". The two languages competing in this space are OpenCL (Open
Compute Language, the open standards option) and CUDA (nVidia specific).
Both have a C-like syntax.

Be aware that even if you're working with a Linux host, there are basically
no FOSS options in this area. AMD, Intel, and nVidia all have stacks that
are buggy in different and exciting ways.
