It's not PC hardware so nvidia is not an option anyway. 2-D curved surface
but keystone would cover the bulk of it I think.


Google threw up a few ideas eventually. Use an Xvfb or Xmem headless server
to prepare a bitmap of the console image. Then use the "real" Xserver to
display this bitmap via a texture mapping that does the distortion.

I know the processor in question has 3D acceleration to do the texture
mapping, but suspect the system hasn't got enough general ommph and ram to
run two X servers in such a tricky configuration.


Still thanks for the input.  I'll pass it on.
