VXIMove returns error 0x8000 only in 64-bit Solaris 8

Question

We are looking to migrate our Solaris CPU to a faster Blade 150 (or better) PCI-based workstation. The downside is that these latest workstations all contain 64-bit  processors so we are forced to run a 64-bit Solaris kernel. According to the NI-VXI documentation, the driver works on 32-bit and 64-bit kernels so I was not too concerned. Unfortunately our applications are not working properly when using the VXImove API call to move a chunk of data from VXI to a local memory address. The error is always 0x8000.
We eliminated Solaris 8 as the problem by duplicating the setup on an Ultra 10 workstation which is also PCI-based but runs 32-bit Solaris 8. The same drivers were used in both cases. The VXImove works properly when running in Solaris 8 32-bit.
I have attached my resman output  files for reference. Thanks in advance.

Hello All,
I would like to clarify one of the statements made earlier in this forum.  NI VXI is not supported as a 64-bit application, under any circumstances.  One can user NI VXI on a 64-bit system, but they must run it as a 32-bit application in order for it to function correctly, and therefore lose the 64-bit processing capability. 
It is true that NI-VISA is simply an added layer between the driver and your application.  As KnowledgeBase 2QDASEPG: Supported NI-VISA Operating Systems and Features points out, NI-VISA only supports VXI functionality on 32-bit operating systems.  This is because the NI VXI driver itself is only supported as a 32-bit application.
