It probably doesn't have the drivers compiled.  Did you look in your 
kernel  config to see if you have non-standard serial port support built 
as a module?  I would google for 'etMos Technology PCI 9835' and see if 
you get any hints on what driver you need.  Also make sure you have 
support for more than 4 serial ports enabled.  Look in your log files; I 
have two Siig CyberSerial cards and depending on the slot and kernel 
version they have shown up as ttyS56 and ttyS57 - so if you only have 
support for 4 serial ports you will never see them.

Serial ports and multi-io cards should be pretty much no-brainers unless 
it's an intelligent card, like an Eicon or Digi.
