Looks like 5162/5163 is fine building wise. Here is what I got for
rdma_lat for a 32-bit server and 32-bit client:

loading libehca   local address: LID 0x0d QPN 0x140406 PSN 0x253f3e RKey 0x2340032 VAddr 0x00000010019001
  remote address: LID 0x08 QPN 0x140406 PSN 0xa79d77 RKey 0x2340032 VAddr 0x00000010019001
  Latency typical: 3.25746e+09 usec
  Latency best   : 3.19975e+09 usec
  Latency worst  : 4.21767e+10 usec

and for rdma_bw:

loading libehca  local address:  LID 0x0d, QPN 0x150406, PSN 0x1b3ee5 RKey 0x23a0032 VAddr 0x000000f7fce000
  remote address: LID 0x08, QPN 0x150406, PSN 0x2fa0a9, RKey 0x23a0032 VAddr 0x000000f7fb8000
  Bandwidth peak (#0 to #999): 4.3446e-07 MB/sec
  Bandwidth average: 4.3446e-07 MB/sec
  Service Demand peak (#0 to #999): 17301 cycles/KB
  Service Demand Avg  : 0 cycles/KB

So it's still present...

Thanks,
