There was a minor bug in the aic7xxx.seq script (actually, it was more like I
failed to take into account a limitation of the parsing program that parses
the binary sequencer code).  It resulting in invalid instructions getting
downloaded to every controller prior to a 7895.  The attached patch should
solve people's problems with this.  (Note, this patch wasn't made against a
full linux tree, so cd into driver/scsi and use patch -p1 in order to apply
it).
