You could try "aic7xxx=no_probe".  Also check the termination on the
bus.  Most probe hangs are caused by termination issues.  Remember, only
the drive at the end of the cable should be terminated--the rest should
not be.

If you can boot up FC4, have a look at the /boot/grub/grub.conf file
and see what parameters are passed to its kernel, then try those on
the install command line.
