 thread, so I can't see where the incriminated instruction resides. I 
 tried qemu-ppc, but it's not good enough to run mono yet. Any other 
 suggestions on how it may be possible to find out the address? 
  
 Lowering MIN_CACHE_LINE did not help, nor did trying a CVS snapshot; 
 same problem there.

+Uhm, if gdb doesn't work on your system, it's a bit hard.
+You may change sigill_signal_handler() in mini/mini.c
+to print to a file the contents of the ucontext. You need to
+cast the ctx pointer to a struct ucontext *uc and then dump the
+registers inside the uc->uc_mcontext.uc_regs->gregs array.
+Take the value of uc->uc_mcontext.uc_regs->gregs [PT_NIP]
+and dump also the memory at that address (+/- about 64 bytes).
