I thought I would chance taking the easy route, by using updates-testing
yum --enablerepo=updates-testing update "grub*" but the version Beta6 
there has the same problems :(

The link you provided is to src rpms only, but there is a 
grub2-2.0-0.37.beta6.fc17 in koji. which involves 3 files,

http://kojipkgs.fedoraproject.org//packages/grub2/2.0/0.37.beta6.fc17/x86_64/grub2-2.0-0.37.beta6.fc17.x86_64.rpm

http://kojipkgs.fedoraproject.org//packages/grub2/2.0/0.37.beta6.fc17/x86_64/grub2-efi-2.0-0.37.beta6.fc17.x86_64.rpm

http://kojipkgs.fedoraproject.org//packages/grub2/2.0/0.37.beta6.fc17/x86_64/grub2-tools-2.0-0.37.beta6.fc17.x86_64.rpm


After downloading, you cannot simply do yum update grub2*rpm because it 
looks for grub2-tools, and you cannot 'yum install grub2-tools' because 
it does not exist!

You have to do:
yum localinstall grub*rpm
then
grub2-install /dev/vda1

Which results in this friendly message:

root@localhost ~]# grub2-install /dev/vda1

/usr/sbin/grub2-bios-setup: warning: File system `ext2' doesn't support 
embedding.
/usr/sbin/grub2-bios-setup: warning: Embedding is not possible.  GRUB 
can only be installed in this setup by using blocklists.  However, 
blocklists are UNRELIABLE and their use is discouraged..
/usr/sbin/grub2-bios-setup: error: will not proceed with blocklists.
[root@localhost ~]#

After rebooting, (grub menu confirmed Beta6), the SAME problems still 
exist, it looks like the patches mentioned the bug report are not 
applied to later versions yet.

I read the spec for grub2 and that speaks for itself.  Grub2 belong in 
room 101.

We need grub1 back especially for simply set-ups like VMs which have no 
use for the unusable features in grub2.

F17 must be the only linux distribution in history in which you cannot 
edit kernel parameters from the boot menu.
