I think this should be working for CPU:
[vmstat-pc-total]
   FNPATTERN vmstat-(.+).rrd
   TITLE Used Physical CPU (Stacked)
   YAXIS pc (100 = 1 CPU)
   -b 1000
   DEF:pc at RRDIDX@=@RRDFN@:cpu_pc:AVERAGE
   LINE1:pc at RRDIDX@#@COLOR@:@RRDPARAM@:STACK
   GPRINT:pc at RRDIDX@:LAST:pc \: %5.1lf%s (cur)
   GPRINT:pc at RRDIDX@:MAX: \: %5.1lf%s (max)
   GPRINT:pc at RRDIDX@:MIN: \: %5.1lf%s (min)
   GPRINT:pc at RRDIDX@:AVERAGE: \: %5.1lf%s (avg)\n

I don't use this graph definitions anymore.

I created an inventory application that knows the lpars running on the pSeries 
and it creates graphs by calling hobbitgraph.sh with:
hobbitraph.sh?host=server1,server2,server3&service=vmstat-pc&action=menu

The corresponding graph definition is:
[vmstat-pc-multi]
   FNPATTERN vmstat.rrd
   TITLE Used Physical CPU (Stacked)
   YAXIS pc (100 = 1 CPU)
   -b 1000
   DEF:pc at RRDIDX@=@RRDFN@:cpu_pc:AVERAGE
   LINE1:pc at RRDIDX@#@COLOR@:@RRDPARAM@:STACK
   GPRINT:pc at RRDIDX@:LAST:pc \: %5.1lf%s (cur)
   GPRINT:pc at RRDIDX@:MAX: \: %5.1lf%s (max)
   GPRINT:pc at RRDIDX@:MIN: \: %5.1lf%s (min)
   GPRINT:pc at RRDIDX@:AVERAGE: \: %5.1lf%s (avg)\n


The result is the same, but you don't have to create the symlinks.
The "-multi+ is added automatically by xymon because you specify multiple 
hosts.

This is the graph definition for entiled CPU capacity:
[vmstat-ec-multi]
   FNPATTERN vmstat.rrd
   TITLE Used Entitled CPU Capacity
   YAXIS ec %
   -b 1000
   DEF:ect at RRDIDX@=@RRDFN@:cpu_ec:AVERAGE
   CDEF:ec at RRDIDX@=ect at RRDIDX@,10,/
   LINE1:ec at RRDIDX@#@COLOR@:@RRDPARAM@
   GPRINT:ec at RRDIDX@:LAST:ec \: %5.1lf%s (cur)
   GPRINT:ec at RRDIDX@:MAX: \: %5.1lf%s (max)
   GPRINT:ec at RRDIDX@:MIN: \: %5.1lf%s (min)
   GPRINT:ec at RRDIDX@:AVERAGE: \: %5.1lf%s (avg)\n
