You are using a RT patched kernel. A kernel without the RT patch doesn't
include "RT", either for uname, nor for CONFIG_PREEMPT, but by using
"threadirqs" as boot option, a standard kernel has some RT abilities too.
As a side note, "cat /proc/config.gz | gunzip | grep PREEMPT" could be replaced
by "zgrep PREEMPT /proc/config.gz".
