But it _is_ in standard kernel sources; see very old commit:
commit ac6ec5b1de5d1d5afcbe88d73c05df71dca0ac39

serial: 8250_pci: add support for MCS9865 / SYBA 6x Serial Port Card
Maybe your problem is related to not having this very recent commit?
commit 333c085e4b0cd9df04b087d29f87969a4e26dfa9

serial: 8250_pci: unbreak last serial ports on NetMos 9865 cards
In any case, I suggest collecting the boot logs relating to your
serial card and posting them here; boot with the latest kernel,
and without any vendor drivers. With the right information,
I suspect people here can fix the driver for your card as well.
Please also include the "lspci [-vvv]" output relating to your
specific card, so that quirks can be assigned to specific cards
if needed.
