I got it to boot by doing a:
grub-install '(hd0)'
the /boot/grub/device.map must point grub to the right location for hd0,
check that once. Also, grub has not been updated in 5.1 at all, so I
would think your problem is not related to the update at all. When was
the last time you rebooted the machine :)
device.map contains:
(fd0) /dev/fd0
(hd0) /dev/cciss/c0d0
However, I've noticed that grub-install is not telling
the truth:
# grub-install /dev/cciss/c0d0
expr: non-numeric argument
Installation finished. No error reported.
This is the contents of the device map /boot/grub/device.map.
Check if this is correct or not. If any of the lines is incorrect,
fix it and re-run the script `grub-install'.
(fd0) /dev/fd0
(hd0) /dev/cciss/c0d0
# grub-install '(hd0)'
Installation finished. No error reported.

(fd0) /dev/fd0
(hd0) /dev/cciss/c0d0
In the first case it says that no errors are reported, however
there's a message from expr that something has gone wrong. The
stage2 file produced by the two commands differ.
If I add a "set -x" to a copy of the grub-install command
and do a diff on the output I get:
...
< ++ tmp_drive='(hd0)'
< ++ test 'x(hd0)' = x
< ++ test x/dev/cciss/c0d0 '!=' x
< ++ case "$host_os" in
< ++ echo '(hd0)'
< +++ expr /dev/cciss/c0d0 - 1
< expr: non-numeric argument
...

< + install_boot_block '(hd0,0)' '(hd0,)'
---
> + install_boot_block '(hd0,0)' '(hd0)'

The machine reboots automatically during the weekend if
a new kernel has been installed, yum update runs daily,
so it has been rebooted.

I have never gotten grub to install to a linux device name. It always wants a
defined drive in the device.map. I always thought I was doing something wrong,
and resolved myself to always check the device.map first.
