Yes, the patch for btrfs support is large but these have been integrated 
into the Fedora package os-prober-1.57 which is in the staging process 
for both Fedora 17 and Fedora 18.  Therefore, they will get a lot of 
testing "real soon now."

To actually exploit the btrfs support, grub2 needs two additional small 
patches (one for basic support and the other for a btrfs volume on 
multiple devices).  The grub2 patches have been forward upstream as well 
as reported to Fedora.
