I updated this morning for the new kernel plus another 30 or so updates.

After rebooting, I got a screen that read just GRUB, then nothing.

Initially I thought that the device.map file might have been the
problem, it had an entry for fd0 in it as the first device, then hd0
as /dev/sda. I edited the file to remove the fd0 entry and tried again,
but still the same result. In the end I re-installed grub again and got
the correct stage 1.5 message before the Grub screen came up.

Generally, editing device.map is not enough. /sbin/grub-install must be invoked to reinitialize the bootloader using the updated device.map file. So, your changes to device.map didn't take effect until you reinstalled grub.

Has anyone else had problems of this nature on updates recently? I
suppose this could have been a glitch but I've never had a boot sector
damaged before in this way in all the time I've been using Redhat and
Fedora,

Not with the most recent set of updates, but both of my servers that use softraid ended up getting a busted grub configuration installed by F9's anaconda, when I upgraded from F8.
