[Beowulf] numactl & SuSE11.1

I'm sorry for my mistake:
the problem is on Nehalem Xeon under SuSE -11.1, but w/kernel 
2.6.27.7-9 (w/Supermicro X8DT mobo). For Opteron 2350 w/SuSE 10.3 (w/ 
more old 2.6.22.5-31 -I erroneously inserted this string in my 
previous message) numactl works OK (w/Tyan mobo).

NUMA is enabled in BIOS. Of course, CONFIG_NUMA (and CONFIG_NUMA_EMU) 
are setted to "y" in both kernels.

Unfortunately I (i.e. root) can't change files in 
/sys/devices/system/node (or rename directory node2 to node1) :-( - as 
it's possible w/some files in /proc filesystem. It's interesting, that 
extraction from dmesg show, that IT WAS NODE1, but then node2 is 
appear !
