Can you describe advantages of using SCHED_ULE on UP? or just link or something.

I just read in the release notes that 5.3-RELEASE has the new ULE

ULE really available?

Not in RELENG_5 and not in RELENG_5_3. There are issues with it. If it is fixed it will come back.

See this line in /usr/src/sys/kern/sched_ule.c:
#error "The SCHED_ULE scheduler is broken.  Please use SCHED_4BSD"


... which of course you can just patch out. :) I'm still using ULE on my (UP) machine, works fine for me.
