Kernel upgrade to 2.6.12 (built-in DVB drivers)

Kernel upgrade to 2.6.12

Before upgrade:
[root@myth ~]# uname -a
Linux myth.donnlee.com 2.6.11-1.14_FC3 #1 Thu Apr 7 19:23:49 EDT 2005 i686 athlon i386 GNU/Linux

Look for latest version:
# yum search kernel | egrep "^kernel"

kernel.i586 2.6.12-1.1376_FC3 updates-released
kernel.i586 2.6.12-1.1378_FC3 updates-released

[root@myth ~]# yum upgrade kernel
