Subject: Intel fakeraid working?

I was trying to use mdadm to activate an intel fakeraid last night and mdadm insisted on activating it as read-only. I could not get it to switch to read-wrte. Today I came across this bug:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/972960
It seems that the kernel OOPSed here:
void md_write_start(struct mddev *mddev, struct bio *bi)
{
int did_change = 0;
if (bio_data_dir(bi) != WRITE)
return;
BUG_ON(mddev->ro == 1);
It appears this is because it wanted to update the metadata, but the array was read-only, so I thought this might be related to what I was seeing, and there is a bug that is preventing the array from correctly going read-write.
Is the Intel fakeraid support actually working yet, or still in development?
