I'm using Solaris and NI-VXI to talk to a VME-MXI-2 without any trouble. One thing you may want to look at is address 0x0C on your bus extender (probably at address 0xC04C) and make sure that the value there is 0x7800. It's 0x1800 on power up, and the two MSBs need to be set to enable the address mapping window and the proper direction. If I forget to set this value, I see the same behavior you do. There may be a way to configure this through NI's software, but I don't use it.
Hope that helps!
