I am using quartus v9.1 and I found that changing "VERILOG" to

"VHDL" in the .sopc file was not sufficient.

I had to find all of the references to "VERILOG" or "verilog" and

change them to "VHDL" or "vhdl" in the following files:

nios2.ptf

nios2.ptf.8.0

nios2.ptf.bak

nios2.ptf.pre_generation_ptf

nios2.sopc

nios2.sopcinfo

sopcb_tb2_nios2.xml

Only then did sopc builder actually spit out a vhdl version of the system rather than a verilog one.

All of the files you listed except the .sopc file are generated by SOPC builder. You can just change the reference in the .sopc file, delete the rest of them, then regenerate the system.
