Note that none of the other entries include the full path to the module.
Try just:

alias scsi_hostadapter aic7xxx

and see how that goes.

I prefer the /etc/modules.conf approach, as I think it's cleanest
(modules aren't loaded until the hardware access is requested, and under
2.6, they will be unloaded when no longer needed), but it's sometimes
difficult to set up just right.  If the aboce still doesn't work for
you, you can use /etc/modules instead - this just contains a list of
modules to load at boot time.  The advantage is that it's simple, the
only disadvantage is that they're always loaded, whether or not you want
to use that piece of hardware at the time.  Just \
echo aic7xxx >> /etc/modules

HTH,
