I just debugged that. Seems that a friendly developer had the idea to insert
the Altivec-only instruction "dssall" into the cpu_idlespin() function
(during 2017). It crashes my G3, so you have certainly a G4.

I will discuss that with him. Probably the solution will be to add an
  if (cpu_altivec)
there.

Then I might be able to check your X-server issue. :)
