Hello, Latest GNOME 3.8 packages hit Testing today and I'm now experiencing the same issue than you on an ia64 workstation (FireGL1 X1 AGP graphics adapter with 256MB VRAM, r300g driver). I'm however less lucky than you as I'm not able to set a wallpaper bigger than 2560x1440 pixels (always get solid blue). It's noteworthy that thumbnails and preview are OK.
As reported earlier on Gentoo [1], I don't think this is a hardware limitation as suggested there, as gnome-themes-* were not updated today and Adwaita wallpapers (that are 2560x1440 in size) were displayed correctly with previous testing gnome-shell{-common} 3.4.2-16 and gnome-shell-extension 3.4.0-2 packages.
