>Description:
1. When updating my chip firmware changes are not saved:

/usr/local/share/cpucontrol/m011067660F.fw: updating cpu /dev/cpuctl0 from rev 0x60b to rev 0x60f... done.
/usr/local/share/cpucontrol/m011067660F.fw: updating cpu /dev/cpuctl1 from rev 0x60b to rev 0x60f... done.

However I get this each reboot. It seems that update doesn't go right. My chip is:

Jul  3 09:01:14 green kernel: CPU: Intel(R) Core(TM)2 Duo CPU     E8400  @ 3.00GHz (3000.01-MHz K8-class CPU)
Jul  3 09:01:14 green kernel: Origin = "GenuineIntel"  Id = 0x10676  Family = 6  Model = 17  Stepping = 6

Jul  3 09:01:14 green kernel: Features2=0x8e3fd<SSE3,DTES64,MON,DS_CPL,VMX,SMX,EST,TM2,SSSE3,CX16,xTPR,PDCM,SSE4.1>
Jul  3 09:01:14 green kernel: AMD Features=0x20100800<SYSCALL,NX,LM>
Jul  3 09:01:14 green kernel: AMD Features2=0x1<LAHF>

2. Isn't it right to change rc script to patch microcode on powering system down instead of patching it when system starts?

 - we can have more stable behavior in case some patch requires a reboot;
 - we don't need to do anything on port update except rebooting.
