Thanks for the reply.  I'll track down that patch and try it tonight.  I 
don't think this program uses safedisc though (I don't have to have the 
cd in to play).  On another note, I found 'INSTR_EmulateInstruction' and 
added some debug.  It looks like the disassembly I posted earlier was 
wrong.  I dumped the data, and put it into gdb, and here is the result.

(gdb) disassemble bar
Dump of assembler code for function bar:
0x080495a0 <bar+0>:     movaps %xmm0,(%ecx)
0x080495a3 <bar+3>:     shufps $0xa,%xmm3,%xmm2
0x080495a7 <bar+7>:     add    $0x90,%eax
0x080495ac <bar+12>:    decl   0x4c(%esp)
0x080495b0 <bar+16>:    movaps %xmm1,0x10(%ecx)
0x080495b4 <bar+20>:    shufps $0x9d,%xmm3,%xmm2
0x080495b8 <bar+24>:    mov    %edi,0x88(%esp)
0x080495bf <bar+31>:    mov    0x64(%esp),%edi
0x080495c3 <bar+35>:    movaps %xmm2,0x20(%ecx)
0x080495c7 <bar+39>:    jne    0x80491b6

I'm now fairly sure it's failing on the first movaps command.  Unless 
someone can direct me differently, I'm going to start looking at why 
that command is showing up as 'privileged'.

Thanks,
Tyler
