today's yum update trashes FC3?

A friend of mine reported that today's yum update trashed two completely separate FC3 machines of his. It would hang during grub load, just sits there with a blinking _

here are the updates that went in today:

gaim-1.1.3-1.FC3.i386.rpm squid-2.5.STABLE8-1.FC3.1.i386.rpm pcmcia-cs-3.2.7-2.2.i386.rpm openssh-clients-3.9p1-8.0.1.i386.rpm openssh-askpass-gnome-3.9p1-8.0.1.i386.rpm openssh-askpass-3.9p1-8.0.1.i386.rpm openssh-3.9p1-8.0.1.i386.rpm openssh-server-3.9p1-8.0.1.i386.rpm postgresql-libs-7.4.7-3.FC3.1.i386.rpm

he reports it rebooted fine before he did the update, and after he did the update, it no longer loaded grub. he had to boot off a grub floppy to recover it.

anyone else notice this?
