Why is the Radeon rx5700xt card using the X6000 framebuffer?

Hey guys,

I get random KPs only when hibernating on Ventura 13.5.2 and they're all the same. I'm running MacPro7,1 with AMD gen4 7000 series iGPU disabled in Bios. I have all power management features disabled. WEG is not installed or in use as its use with my smbios is warned against by the dev.

I've got @ 0 set to ATY,Adder for all 4 ports in DeviceProperties as well as the correct PCIRoot. Interestingly, one of the kexts in backtrace is com.apple.kext.AMDRadeonX6000Framebuffer. But this is not an X6000 card, it's an X5000 card. Weirdly no such AMDRadeonX5000Framebuffer kext exists in S/L/E. Could the use of a framebuffer from the 6000 series cards be a cause of this issue?
