grub2 menu entry for Fedora 16 is not nice

[Peter Gueckel]

Why does the grub2 menu entry list Fedora like this:

Linux, with Linux 3.1.0-0.rc6.git0.3.fc16.x86_64?

Instead of like this:

Fedora 16, with Linux 3.1.0-0.rc6.git0.3.fc16.x86_64?

While os-prober finds other Fedoras on other partitions and shows them like this 
(yes, I have 2 partititions with fedora 16, because I had to do a base install 
to rescue the system after the grub2 accident about 10 days ago):

Fedora release 16 (Verne) (on /dev/sda6)
Fedora (2.6.40.3-0.fc15.x86_64) (on /dev/sda7)
Fedora (2.6.40-4.fc15.x86_64) (on /dev/sda7)
etc.
