Ummm... but the MPC8xx CPM options _definitely_ have  zero  influence
on  the  behaviour of the MPC5200 PSC UART driver. This is completely
different hardware.

No, it will NOT work. I repeat: the existing driver DOES NOT  SUPPORT
hardware  handshake, so no matter what you do (short of extending the
driver) - it will not work.

Sorry, but it doesn't.
