I double checked the documentation and I think you're right, I can
update the patch. Thanks for pointing it out.

Where? In BAR0?

I tried to follow the CODING_STYLE file, but I might have got it
wrong, I can change that.

The documentation is available online:
http://www.tews.com/Products/ArticleGroup/TPCI/TPCI200.html
http://www.mvme.com/manuals/IP-OCTAL-232_UM.pdf
http://www.alldatasheet.com/datasheet-pdf/pdf/19123/PHILIPS/SCC2698B.html
I'm not familiar with qtests, should I take a look at it?
In my blog post (see previous e-mail) there's a brief explanation on
how to test it. I can provide with a compiled Linux kernel with the
necessary drivers for the guest system if it helps.
A quick way to test it is to redirect one of the IP-Octal serial ports
to a pty in the host and open minicom in both sides.

I'm open to suggestions.
And answering Andreas, yes, the device could be renamed as
'ipoctal232' :)
Thanks,
