Hmmmm...I'm running a 25xx in a lab which supports ospfv3:

Cisco Internetwork Operating System Software
IOS (tm) 2500 Software (C2500-IS-L), Version 12.3(13a), RELEASE SOFTWARE

routerV6(config)#ipv6 router ?
  ospf  Open Shortest Path First (OSPF)
  rip   IPv6 Routing Information Protocol (RIPv6)

Have 32M/32M memory which is max for these boxes.  Admittedly I am just
using this box as an isolated lab tester so have limited real routing
traffic for this particular box [only bgp for v6 is configured so
