Like I said, the aic7xxx and aic7xxx_old modules have been around a long 
time and the 'old' module can still be built from the 2.4.20 kernel.

Look around your 8.0 system and I am sure you'll find them both.

Personally I hope the kernel crew never gets rid of aic7xxx_old since it 
was always rock solid.


However, since your controller isn't seen at all by the boot, I think you 
must have a different problem.  The problem with the new aic7xxx was 
that it *tried* to work with the controller but just got lots of 
timeouts and other errors.
