Subject: [BUG] serial base baud misdetected in 2.6.27

I'm running an ATCA7101 board.  This board has two 16550 ports that get 
detected as ttyS4 and ttyS5.

With a much earlier kernel (2.6.14) the serial port base speed is 
correctly detected as 230400, which gives the desired 115200 when I 
specify that on the kernel commandline.

With 2.6.16 and 2.6.27 (not sure about the intervening kernels) the 
serial port base speed is detected as 921600, which means that I need to 
specify 460800 on the commandline to get a real speed of 115200 (as 
verified by an external terminal server).

Any ideas what could be causing this misdetection?  I'm having lab 
issues right now so I can't track it down, but I'll have a go at it
