No RAID support? [Fixed]

[Windy]

Just tried the JJ Beta build... With Alpha 6 (CD) I could install onto my Motherboard (fake) RAID, but with the Beta it just hangs on loading the partitioner if I enable RAID; has Motherboard RAID support been dropped?

Edit:
Fixed, but I'm a little confused...
It worked OK in the Alpha, didn't work in the Beta, but works OK in the release?

Re: No RAID support?

Tried again, this time pre-partitioning and formatting the array, this time it recognises the partitions and installs OK but falls-over on installing Grub.
