I tested the patch series and it does not appear to make a difference
for the internal (16550A) serial ports on my system. Also, I am still
unclear on why it freezes the X display during the timeout period.
The other serial port device I have at hand is a FTDI USB->Dual UART
which appears to not have a timeout at all, but then that shows no
difference whether your patches are applied or not. I don't remember if
it was always that way, at least 2.6.39 also acts identically.
