The 'W' is probably what he is reading off of the silk-screen on the 
chip, and has no real significance.

Having up-to-date firmware for your drives is critical, as is making
sure that you have solid cabling.  Certain revs of the 7902 are geared
for backplanes, and others are geared for cables, and neither likes
having both backplanes and cables in the same chain.  68->80 pin
converters are also typically very troublesome.  So keep your cable
configuration as simple and as in-spec as possible.
