I realize I'm an edge case and my scenario is not ideal (I use an ITE controller and performance is actually impressively slow), but I cannot boot 9.0 from my stripe, even after manually loading ataraid from the loader prompt (after running an unload command).  I mention it mostly because other people using the fakeraid setup by their motherboards for whatever reason (perhaps to share a partition table with windows on the same mirror or stripe) may have a similar problem.  It seems like the ar0 device disappeared for me completely (even though it finds ada0 and ada1).  I'm using the following device:

I haven't looked too much into it (these devices are actually PATA not SATA, so AHCI doesn't even exist for these), but maybe there's an ATA/AHCI driver that's built into the default kernelthat is interfering with ataraid.ko?  Maybe this interferes with my stupidly slow and unpopular configuration.

Hmm, I may just as well dump the UFS and restore it to a totally geom based solution.  If anything it will likely help rather than hurt my performance.
