+       - 'SUNW,n2-rng' for Niagara 2 Platform (SUN UltraSPARC T2 CPU)
+       - 'SUNW,vf-rng' for Victoria Falls Platform (SUN UltraSPARC T2 Plus CPU)
+       - 'SUNW,kt-rng' for Rainbow/Yosemite Falls Platform (SUN SPARC T3/T4), (UltraSPARC KT/Niagara 3 - development names)

+Node 0xf029a4f4
+       .node:  f029a4f4
+       rng-#units:  00000002
+       compatible: 'ORCL,m4-rng'
+       reg:  0000000e
+       name: 'random-number-generator'
+
+/* solaris on SPARC M7-8 */
+Node 0xf028c08c
