ETR on ppc, pic 0

I know, I know - yet another bug of something not working on ppc. But actually things have improved in the meantime. Since a complete system & kernel rebuild with gcc 7.3.0 my AGP Radeon 9650 and 9800 started working decently (see bug #105254). And mesa 18.0.0_rc4 certainly shows less glitches than 17.2.x and the versions before. Colors are right and Extreme Tux Racer runs smoothly.

What's not working is transparency and the background is missing too. Another thing is this strange misplacement of trees and the start/finish banner on the track (lying on the side instead of standing).

I'll add pictures, you will notice immediately what I mean.

Just tried software rendering for comparison. Using softpipe ETR runs like on amd64 without any glitches. Albeith unuseable slow on a G5.

Tried a Radeon HD 6450 on my PCIe PowerMac G5 11,2 for another comparison. Graphics are rendered correctly! So it seems this bug is a specific r300 driver problem, not a generic Big Endian problem.
