Linus, Andrew,
This patch adds initial support to 8250-pci for the Korenix Jetcard PCI
serial cards. The JC12xx cards are standard RS232-based serial cards
utilising the Oxford 16C950 device.
The JC14xx are RS422/RS485-based cards, but in order for these to be
supported natively, we will need additional tweaks to the 8250 layers
so we can specify some values for the 950's registers. Hence, these
two entries are commented out.

IIRC 16c950 just need two bits in ACR set properly. Will attached patch
do the trick ?

I, too, also have a patch which does something similar. I'm going to
hold off on that until post 2.6.20 though, especially as I have no
way to test it.
