SCSI card advice (again)

Thanks to those who responded to my earlier message. I decided to buy the
ASUS PCI SCSI card (since I got a good deal on it). However, it has a
Symbios Logic 53c810a chip which caused my 2.0.30 kernel to hang with a
"scsi bus busy" error during the SCSI host probe. Fortunately, after
patching to 2.0.33, the kernel successfully recognised the card, but
I got a (hopefully, minor) warning that the chipset revision was greater
than 2 (I've included the text of this warning at the end of my message). Is
this anything to be concerned about (maybe I should use one of the 2.1.x
kernels which I understand have a 53c810a driver) ?

On another note, does the scsi card become associated with any particular
/dev file or are the disks, scanners, CD-Rs, etc. on the SCSI chain the ones
that receive a device file (I know the 1st disk would be /dev/sda) ? I
understand that I have to do a 'ln -s /dev/sga /dev/scanner', but what is
sga associated with (I'm assuming it's the card itself) ? I'm also a bit
fuzzy regarding SCSI termination: The manual states that termination is
required on the end device, but I was told that I don't have to worry
about it (auto-termination). Does the scanner have to be switched on
before I boot-up for association to /dev/sga to take place or will SANE
detect the scanner itself ? Finally (for the sake of argument) if I put 2
scanners on the SCSI chain how could I associate both with sga ?
