[LAD] [OT] Real-time threads on openSuSE 11.4

My ex-collegues at Alcatel are screaming for help. They want to run
an app (as root, debatable but that's another story) using SCHED_FIFO
threads on an openSuSE 11.4 system.
Using the 'default' kernel (which has CONFIG_PREEMPT not set), this
works. Using the 'desktop' kernel (CONFIG_PREEMPT=y) they get an
EPERM when trying to start a RT thread, even as root.
As I haven't used SuSE for ages, has anyone an idea of what is
happening here ?
A world of exhaustive, reliable metadata would be an utopia.
It's also a pipe-dream, founded on self-delusion, nerd hubris
and hysterically inflated market opportunities. (Cory Doctorow)
