No, it doesn't work:

x4 ~ # rdmsr -a 0x00000410
3fffffff                                    
0                                           
0                                           
0                                           
x4 ~ # wrmsr -a 0x00000410 0x3ffffbff
x4 ~ # rdmsr -a 0x00000410
3ffffbff                                    
0                                           
0
