USB buses deregister themselves on boot

Hello,

I'm running FC1+Updates, with a self-compiled 2.4.22-1.2199.nptl
kernel.

On bootup, the USB busses seem to deregister themselves and remove
the relevant modules.  A snippit from dmesg shows this ...

BUT, if I wait for the system to finish booting and manually
load usb-ohci by hand as root, the attached USB
devices are loaded and any appropriate modules are loaded ...

Why the difference?  How do I get the system to autodetect the attached
devices and load the appropriate modules automagically?

usbcore is compiled into the kernel, but usb-ohci and ehci-hcd and device
drivers are modules if that makes any difference.
