radeonkms broken on PowerMac G5 (powerpc64) #309

Describe the bug I have a PowerMac G5 (powerpc64) and an old Radeon card in it, which I tried using with the radeonkms driver (scfb worked fine, but slow).

DRM KMOD version Paste the output of pkg query -x '%n %v' 'drm.*kmod' drm-510-kmod 5.10.163_8 This was the only drm-kmod version available through pkg for this machine.

To Reproduce

# pkg install drm-510-kmod gpu-firmware-radeon-kmod-r300-20220511
# kldload radeonkms

now you should see yellow vertical stripes on a black background.

Screenshots sceenshot

The screenshot is when I run kldload radeonkms && startx. On X the colored rectangle is the cursor, which I can freely move around. It's not shown, when I only run kldload radeonkms.

Additional context This machine is big-endian, which might be a possible reason for this.
