Hi John,
Trust me, with kernel 2.6.32-71.29.1.el6.x86_64 it works like a charm. 
It is true I had to detect by myself the IO port the BIOS assign to the 
card and that's all. As I don't have to change daily the card to a 
different slot, everything works if I load the driver parport_pc with 
parameter io=0x2018.
I was able to do this because if I type lspci, the operating system 
detects the card. The problem comes when I start with kernel 
2.6.32-131.17.1.el6. Then lspci does not not show the card in the right 
way. Instead a message with the text "!!! Unknown header type 7f" 
appears in the section of that card.  :(
