Dear W1zzard, is it not possible that the kernel mode driver detects when it come back from a standby condition and automatically load a custom profile?
I don't think it is completely right that the lock coming from standby is solved when the divider is > 4.5.
1) My 9800pro has default divider of 4
2) My X800PE doesn't resume properly with actual divider that is 8.5. When I will come back home from vacation I will check the bios default divider following my procedure described in the above message and let you know.
