It's likely to be quite specific to either your CPU, or other hardware
drivers. If it was a general problem it would almost certainly have been
spotted by someone else.

What happens if you run two copies of fptest in parallel on the text
console? This would fail if it was a general fpsave/restore bug. Your
problem seems to be quite specific to also having the framebuffer
active. What kernel modules is your X server using?
