By this do you mean that when you have the card in the system, FreeBSD 
booted and you kldload the driver, you don't see kernel messages showing 
the appropriate attach messages?  Is anything printed?

As Daniel and Warner already stated, the PCI rescan is automatic.  This 
is more likely an identification or driver mismatch problem.  Please 
provide the following:

- The exact make and model of the HBA card.
- The exact version of FreeBSD you're using.
- Which driver you're trying to use.

This information will allow us to nail down possible reasons why the 
attach is not occuring.
