Subject: problem with "serial" driver in kernel 3.16.0

We are a small company FAST ComTec GmbH 
(www.fastcomtec.com) and produce multichannel analyzers 
with Windows software. I am the software developer and 
would like to get our software working also under Linux 
with the help of WINE.

I was already successfull with our USB devices and most
of our PCI cards, but with one of the PCI cards 
it does not work (in Debian v8, kernel 3.16.0).

Our PCI cards have a AMCC controller S5933, we use the 
standard AMCC vendor id 0x10e8 and device id 0x8226, 
device class serial. Most of our cards use two I/O port ranges 
and an interrupt. I have written a linux driver for these cards 
and could get everything working, but the interface card 
for our MPA-3 multiparameter system uses only 
one I/O port range and an interrupt. This card is recognized 
by the "serial" driver in the kernel as a serial interface card 
and there is no way to load our own driver.

My question is, could you remove in future kernel versions 
the support for this card in the kernel our make it possible 
to blacklist it in /etc/modprobe.d/fbdev-blacklist.conf
like other drivers that are not directly included in the kernel?

With best regards
Wolfgang Wilhelm
