Eric,

Try installing (not upgrading) to the Rawhide (FC4) kernel.  I've got
rawhide running here at 2.6.11-1.1177_FC4.  Download the proper kernel
RPM from:

http://download.fedora.redhat.com/pub/fedora/linux/core/development/i386/Fedora/RPMS/

Run rpm --test -ivh kernel-<whatever>.rpm.  The test
option should tell you whether there are any additional dependencies.
If that passes then remove the --test option and run again, to actually
do the install.  Doing an install instead of an upgrade will preserve
your earlier kernel versions.

Bob...
