raid not autostarting after kernel update

http://forums.fedoraforum.org – Howdy. I updated my fc12 x86_64 server today, and one of the updated included kernel 2.6.31.12-174.2.3.fc12.x86_64 from the previous one of kernel-2.6.31.9-174.fc12.x86_64. When I boot with that kernel, it stops when my logical volumes that are built on a raid 5 array (linux software raid built using mdadm) are not there. I can start them afterward with mdadm --auto-detect which seemingly loads the appropriate modules and starts the array, but I have never had to do this before. Reading the mdadm man page, it mentions that this is generally done by the initrd. So, I am guessing the initrd that came with the new kernel is missing something. Help? (HowTos)
