I have a Tekram DC-390U2W controller card with a Seagate HDD hooked up to it
in my desktop box. Here is the output from lspci -vv:

And the output from lshw:

I also have two IDE hard disk drives installed. I use the SCSI drive to run
various flavors of Linux as well as Windows 2000 (although I've been
seriously considering wiping out that Windows partition as I haven't touched
it in a year). Every Linux distro that I have tried has been able to
automatically load the correct drivers and utilize both the Tekram card and
SCSI drive. The only tiny issue that I run into occassionally is that grub
is configured incorrectly during installation because of the presence of the
two IDE drives (the SCSI drive is percieved as hd2 during install but hd0
during boot).

Consider reading this SCSI guide to familiarize yourself with choosing and
setting up the hardware:
