Please document this loudly in the UPGRADING file.  It caught me  
totally by surprise that the console speed was now 9600.  I thought I  
lost my serial console since the BIOS was booting up at 115200.  If  
it weren't for the other error (ACPI) keeping the kernel from  
booting, I would have realized it *before* I drove down to the office  
late saturday night.  See, I needed a serial console to disable part  
of acpi for debugging.... :-(

Anyhow, please, please document this in UPGRADING so others won't be  
bitten by it.

Thanks!
