Don't know what "G5 HD Radeon cards" are (first Radeon HD cards were released in 2007 and there's no PPC ROM for any), but "HD Radeon" cards (HD2350 to HD7670, HD8350 to HD8490, R5 210 to R5 310) will require bigfoot's R600 driver project to be finished first, right? So, TinyRave will benefit TinyGL-supported R300 to R500 (Radeon 9500 to X1950) before this.
