I would suggest you to go ahead with express setting and setup router to the configuration you want. Once you have visibility then check the hardware, version and go for specific commands to set the console speed.
Usually console port speed is 9600 BAUD and to access through any terminal emulation program. Once you are in the router config you have good flexibility to analyse and set configuration to your wish
I know this is a little old but just went through some of the same scenarios.
I have a 3750G with the same problem. I had sped up one last week to 115200 to copy over a *.bin and then set it back to 9600 with no problems.
Today I found a switch in our spares that is set to 115200. I tried to change the speed at the Console port and after reboot found it went back to 115200.
So, I tried what BlackHawk08 suggested, in another post, by going into ROMMON by holding down the mode button during boot. The set BAUD 9600 did not work. But the unset BAUD did work. I then did flash_init waited and then type boot and waited. The switch rebooted and came up at 9600. I then did a show run and the Console port is no longer at 115200.
So, I've been able to change the speed on a switch to copy the IOS over and set back successfully and fix a switch that had been changed to 115200.
