PATCH 1/1 Serial MRi MRI-PCIDS1 dual port serial card

This trivial patch against 2.6.11.6 adds support for the MRi PCIDS1 dual port serial card. This card is a little controversial since it is the subject of a PCI vendor/device ID clash. (See
http://www.ussg.iu.edu/hypermail/linux/kernel/0303.1/0516.html). I have for now just used the hex ID 0x950a. The divisor was part calculated part iterated, so may not be exactly correct (but works for me at all settings between 300 - 115300 bps).

Cheers
David
