It seems X4500 (not available anymore) had Marvell SATA controllers, that are not supported with RHEL5.
And those marvell controllers caused major grief for Sun, especially when Solaris added support for NCQ somewhere in there. under heavy IO workloads, the controllers would just hang. Some nasty bugs. Driver software workarounds caused a big performance hit.
Is that a different chipset than http://www.newegg.com/Product/Product.aspx?Item=N82E16815121009 uses? I replaced a Paradise and Adaptec card with one of these (or maybe the PCI-E version) and Centos recognized it and worked better than with the two different cards.

it's fakeraid. I don't know if it's a different one than what was in there previously though..:)
