[CentOS] Marvell Yukon 8056?

Greetings list-

I've got a server 'in the mail' and I see now on the specsheet that it has Marvell Yukon 8056 NICs onboard. Since I cannot seem to find a HCL for Centos 5 or RHEL5 to help verify, I'd like to know if it works 'out of the box' on CentOS 5.x or is there additional work to make it function (properly)? 

My searching has revealed that there are in fact two different drivers for Marvell hardware... sky2 and sk8lin?

Any pointers, tips, experiences, etc appreciated. Thanks!
