I tried updating to an update-testing kernel for F13
kernel-2.6.34.3-37.fc13
http://koji.fedoraproject.org/koji/buildinfo?buildID=189280

but it fails, because linux-firmware is too old:

[root@kovinek ~]# yum --enablerepo=updates-testing update kernel\* linux-firmware\*

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest
