That's not at all the case. X has, for a long time, used the intel specific
ioperm calls to use cli/sti in user mode.
The RTLinux patch, at one time, caught ioperm calls and complained. But we found
that the number of X-servers that used this feature was small and dwindling, and
the problem became not significant. I don't know if the new X makes the mistake
of going back to this design - I suspect not because ioperm is totally non-portable
out of x86.
My suggestion is that you recompile X with this macro set to false - so that X doesn't
try to disable irqs and see if that fixes your problem. I suspect that this is not
your problem.
