Boot time error involving mptbase and mptscsih

At boot time, on a completely patched FC1 with kudzu off, error messages
appear concerning mptbase and mptscsih. I didn't notice any of these
messages before I ran a yum update to grab all the patches.

The modules.conf contains 2 relevant lines:
	alias scsi_hostadapter 3w-xxxx
	alias scsi_hostadapter1 mptscsih

This box has a 2 channel SCSI on the main board that currently has nothing
connected to either channel. The 3Ware Escalade has all the drives connected
to it. The Box's BIOS (ASUS PR-DLS533) has the SCSI BIOS turned off, and yet
something has located the hardware anyway.

After the 3WARE drivers are loaded, it attempts to load mptbase and fails
once per channel on ioc0 and ioc1 bringup. 

Then I get a slew of :
/lib/mptscsih.o unresolved symbol mpt_blah_blah_blah 
and finally:
ERROR /bin/insmod exited abnormally.

I've tried commenting out the mptscsih line in the modules.conf and also
tried 	alias scsi_hostadapter1 off	but neither worked.

I'm not sure what builds the list of things that insmod is going to attempt
to load. What's the correct way to tell the O/S not to attempt to load
mptbase & mptscsih ? If I'm reading what man modules.conf says, then "off"
is supposed to do it, but it doesn't. 

If in the future we do need to use the SCSI channels, how do I put things
back?
