cirrus can handle 1024x768 (and slightly higher) with 24bpp depth. cirrus can handle up to 800x600 with 32bpp. The problem with 24bpp is that it is a rather unusual depth these days, cirrus is pretty much the only relevant device still using that, and it is a endless source of issues. Wayland doesn't support it at all. Bugs in Xorg keep showing up. So using 32bpp by default is the better choice IMO, even if it comes with the drawback that the resolution is 800x600 only. But hey, better a working 800x600 display than a broken 1024x768 display ...
