I'd go to the Serial Howto
http://www.linuxdoc.org/HOWTO/Serial-HOWTO.html

There's a very important section in that document which talks about
PCI/ISA PnP and non-PnP cards.  You may want to try disabling PnP in the
BIOS and see if that helps.  But I encourage you to take a look at
the document I mentioned... it may help you in troubleshooting.
