latest update to FC3-test1 hoses the system

[Nave, Ronald]

I just finished updating my system this morning and now find that modprobe
generates a segmentation fault when I boot up

As a result I can not load drivers for CD rom , floppy disk ,  ethernet card
, or USB memory sticks .

The system boots up , but there is no way to load new files onto the system
to undo the mess I have gotten into.

It looks like I may have to reformat and start over.
