Lion and Pro and Apple RAID, solved?

When Lion came out I avoided it because of the huge quantity of people with Mac Pros and the Apple RAID card who posted issues. Now that I've got IOS 5 on my iPhone and iPad I am being "encouraged" to upgrade to iCloud from MobileMe, however this requires Lion on my Pro. My Pro is relatively new (late 2010), Westmere processors, 4x 2TB drives on Apple RAID card in 0+1. Is Lion now "fixed" for this setup? Or am I just between a rock and a hard place?
