Sorry for the obvious question - but have you enabled the new MSR 
instructions in the hardware build (and platgen tweak) - as per below?

The only catch is that a gremlin in EDK6.2 (and also SP1 alas) means 
that you have to twiddle your microblaze.mpd file to allow you to set 
the C_USE_MSR_INSTR parameter.  It's trivial:

edit
/edk6.2/hw/XilinxProcessorIPLib/pcores/microblaze_v2_10_a/data/microblaze_v2_1_0.mpd

add a new line (somewhere around line 50, among the other PARAMETER 
declarations, doesn't matter):

PARAMETER C_USE_MSR_INSTR = 0, DT = integer

Finally, edit the system.mhs file of your favourite mbvanilla target, 
and add the following in the microblaze_0 block:

PARAMETER C_USE_MSR_INSTR = 1
