cirrus can handle 1024x768 (and slightly higher) with 24bpp depth. cirrus can handle up to 800x600 with 32bpp.
16bpp is maybe a better choice? Nobody's using cirrus because they care about color fidelity and it'll use less CPU to update. There's precedent here, mgag200 defaults to 16bpp on sufficiently memory- impaired devices.
Yeah nouveau does the same fallback to 16bpp if there's not enough vram. So do a bunch of other drivers.
Makes sense. But appearently 16bpp support bitrotted over time, when just flipping the default the driver Oopses at init time. I'll look into it.
