Sorry the debug -g option did not help.
I have only noticed increased speed with 6 vs 5.4, but then again I am
not using X, I use FreeBSD only for servers.
I noticed a slight lag at first and was not using the SCHED_ULE
scheduler, but the 4BSD.
Removing debug -g and recompiling my kernel pretty much solved that.
