Although the overall structure of the file is very different from EDK 7.1, and many names are different when using the xps* IP in EDK 9.2, the names that are used by the kernel (in arch/ppc/syslib/virtex_devices.c) should be defined correctly (as long as you use the linux-2.6 BSP). Under no circumstances would I ever recommend editing that file by hand. If you modify the design, you should regenerate the xparameters file and copy it into your kernel. Furthermoe, the file that is in the kernel is for a standard reference design, and unless you are using this reference design, you *must* copy the xparameters file for your design. The kernel from git.xilinx.com already has all the drivers, all you need is the one file.
