Will ATTO UL3D (OEM) CARD WORK WITH OS X 10.5?

I had an Atto UL3D (OEM) scsi card installed when I purchased my Dual 2 Ghz PowerPC G5 from new, and so far it has worked through all upgrades to Mac OS X 10.4.10.

I am now planning to upgrade to Leopard.

Atto have stated to me that the UL3D is an end-of-life product, and don't really know if their driver works. However, the Atto UL4D and UL4S are supported with Leopard.

Does anybody know if the Atto UL3D scsi card will work after I install Leopard?
