chips (some non-HiQV variants)
cirrus alpine except 5480 and 7548
vesa (if no 32bpp modes advertised in vbios)
vmware (if the host is 24bpp)

Everything else appears to have 32bpp support (or doesn't support depth
24 period), although admittedly on older kit you may be running into
memory limits.  I still think that in any environment using Render
you're going to be better off with a blitdown in shadowfb.

Meh.  If we don't do this I'll just fix building 24bpp support out.  I'm
perfectly willing to say that 24bpp-only chips are too short to ride.
