Fedora Users — any reason for things SMP on a single processor

I think I misclicked in Yumex, and installed some stuff that has no business on this machine, but I don't want to compound a problem by doing something dumb. I have a single processor system, and I noticed there were a couple of smp packages on my system after what I thought was an upgrade, but turned out to be an install:

rpm -qa | grep smp
GFS-kernel-smp-2.6.11.8-20050601.152643.FC4.2

Which has resulted in this:

cat grub.conf ...........snip header/hashed stuff title Fedora Core (2.6.11-1.1369_FC4smp) root (hd1,0) kernel /vmlinuz-2.6.11-1.1369_FC4smp ro root=/dev/VolGroup00/LogVol00 #rhgb quiet initrd /initrd-2.6.11-1.1369_FC4smp.img title Fedora Core (2.6.11-1.1369_FC4xen0) root (hd1,0) kernel /xen.gz module /vmlinuz-2.6.11-1.1369_FC4xen0 ro root=/dev/VolGroup00/LogVol00 #rhgb quiet module /initrd-2.6.11-1.1369_FC4xen0.img title Fedora Core (2.6.11-1.1369_FC4) root (hd1,0) kernel /vmlinuz-2.6.11-1.1369_FC4 ro root=/dev/VolGroup00/LogVol00 #rhgb quiet initrd /initrd-2.6.11-1.1369_FC4.img title XP rootnoverify (hd0,0) chainloader +1

Is there any reason I shouldn't rpm -e these two SMP packages?
