Server :: How To Permanently Remove A Module From Kernel

I got this problem where my USB ports don't work. So if I do the command:

modprobe -r ehci_hcd

it fixes it. I can put it in the /etc/rc.local so that it runs every time when the server reboots. But, I want the ehci module removed without ever being loaded because sometimes the server goes through an fsck and the module is loaded and therefore I cannot use my IPMI to access the server.

I believe that my kernel has it within it because blacklisting the module does not work. I've tried remaking the initrd with this:

add module to /etc/modprobe.d/blacklist
mkinitrd -f /boot/initrd-$(uname-r).img $(uname -r)

and that didn't work. I've searched on how to do it but nothing is really clear. I would like to know what the command would be to do this. I use Fedora 8.

I would like the ehci_hcd module to not be loaded so that if the server goes through an fsck, the module is still not loaded.
