OCLP 1.4.3 on 2008 Mac Pro not able to root patch

Wondering if anyone can help me get things straightend out. I was able to get Sonoma (14.4) up and runing on my 5,1 2008 Mac Pro using OCLP (after much struggle). Attempted to go to 14.4.1 and let OCLP do its thing with root patching prior to attempting to update to 14.4.1 and things went afoul. I have a radeon 580 installed and it runs in limp home mode on 14.4 (can't update to 14.4.1). Every time I attempt to install the root patches with OCLP 1.4.3, the "rebuilding Kernel Cache" operation fails with error code:

"Reason for Patch Failure (71): Error Domain=KMErrorDomain Code=71 "Unable to resolve dependencies: 'com.apple.kext.AMDRadeonX4000' names a dependency on 'com.apple.iokit.lOAcceleratorFamily2, which was not found."

Can anyone point me in the right direction here? Thank you in advance!
