Change
set root=(hd0,2)

set root=(hd0,1)
Change

search --no-floppy --fs-uuid --set UUID_of_sda1

to
linux /vmlinuz-2.6.30.9-90.fc11.i586 ro
Change

to
root=UUID=UUID_of_sda2 rhgb resume=/dev/sda3
Change
initrd /boot/initrd-2.6.30.9-90.fc11.i586.img
to
initrd /initrd-2.6.30.9-90.fc11.i586.img
(What does "resume=/dev/sda3" do?)
You can either change these lines in /boot/grub/grub.cfg (but keep a
backup because it will be overwritten the next time that grub-mkconfig
is run) or chmod -x /etc/grub.d/30_os-probe and add your Fedora
entries into /etc/grub.d/40_custom.
# cat /etc/grub.d/40_custom
