What happens if you run two copies of fptest in parallel on the text

They work perfectly.
Your
problem seems to be quite specific to also having the framebuffer
active.
If by "framebuffer" you mean "kernel fb driver", it doesn't use that.
The X server just talks to the graphics card directly.
What kernel modules is your X server using?
As far as I know, it isn't using any. I've specifically deselected agp
at kernel compile time.
My suspicion is that there is some unusual code path where the FP
save/restore doesn't work, and the fact of konsole doing large amounts
of text rendering (which, I believe, involves FP calculations) and/or
scrolling, makes this code path more likely. (The window that is rendering
doesn't have to be the tty of fptest. Any konsole window that's displaying
a large amount of scrolling text is enough to trigger it.)
