Performance counters are in sysperfinfo on SQL 2000 and
sys.dm_os_performance_counters on SQL 2005, but I could find the item
you are looking for in these views.

But I saw in Books Online for SQL 2005 that these values are cumultative. To
get the present value, sample with some interval. I guess you could to
the same: query @@CPU_BUSY twice with a second or so in between.
