[CentOS] Anaconda doesn't support raid10

So after troubleshooting this for about a week, I was finally able to 
create a raid 10 device by installing the system, copying the md modules 
onto a floppy, and loading the raid10 module during the install. 

Now the problem is that I can't get it to show up in anaconda.  It 
detects the other arrays (raid0 and raid1) fine, but the raid10 array 
won't show up.  Looking through the logs (Alt-F3), I see the following 
warning:

WARNING: raid level RAID10 not supported, skipping md10. 

I'm starting to hate the installer more and more.  Why won't it let me 
install on this device, even though it's working perfectly from the 
shell?  Why am I the only one having this problem?  Is nobody out there 
using md based raid10?
