So what will it take to get kernel preemption support added? :)

preempt-kernel has been in 2.5 since 2.5.4-pre.  The work required to
add it to the SH architecture is fairly minimal, with most of the work
being in entry.S.  If you look at MontaVista's (Jeremy Siegel's) SH
preempt support for 2.4, the work for 2.5 is about the same.  The main
difference in 2.5 is the use of the thread_info structure for
preempt_count and that the interrupt return path no longer calls
preempt_schedule, but schedule itself.

I'd be happy to help ...
