Promise FastTrak S150 TX2plus PDC20371 - another new offset?

I'm a newbie and I hope I've posted in the right place!

When I run any dmraid command in Ubuntu Feisty Fawn, I just get "No RAID 
disks". dmraid doesn't seem to find any metadata at all - so I went looking 
for the metadata on the last sector of my disk. From reading the list it 
seems that there are a number of different config offsets and I am wondering 
whether my metadata matches one of these offsets or is a new one. Help? :)

I've posted my partition table information and a hexdump -C of the last 
sector of my drive over on launchpad:
https://bugs.launchpad.net/ubuntu/+source/dmraid/+bug/112402/comments/8

I'm using...
dmraid 1.0.0.rc13-2ubuntu3
sata_promise driver version 2.01
kernel 2.6.20-15

Thanks guys for all your hard work on dmraid!
