QEMU since 5.0 has two new video devices rage128p and rv100.
These emulate ATI Rage128 Pro and Radeon GPUs respectively,
at least to some extent. This can be useful for OS without
virtualisation drivers or support for VBE or the old Cirrus
emulation.

Are you sure about the QEMU version?
The way you check it (presence of 'ati-vga') says it's available
since 4.0.0.
commit 862b4a291dcf143fdb227e97feb7fd45e6466aca
hw/display: Add basic ATI VGA emulation
git describe: v3.1.0-2677-g862b4a291d contains: v4.0.0-rc0~39^2~1
If they were present in QEMU before 5.0, but unusable, we
need to find a different way to set the capability.

Ideally, this would be split in multiple patches:
* The QEMU capablity addition:
src/qemu/qemu_capabilities*
tests/qemucapabilitiesdata*
* XML parser/formatter:
docs/schemas/
src/conf/*
tests/*xml2xml*
* QEMU command line formatter
the rest
But this is an enum addition, so our compile warnings require
that the two last steps are squashed together. But having the
capability separate means less changes in the main patch
and easier rebasing if multiple people add a capability.

Missing xml2xml test is not such a big deal for just another enum value,
but please take a look at qemuxml2argvtest and add a test case
to verify that it actually creates the commandline you want.
Once you create a domain XML using the device in qemuxml2argvdata,
it will automatically be checked against the schema thans to
virschematest.
By setting VIR_TEST_REGENERATE_OUTPUT=1 before running the test,
it will overwrite the expected output file with what it actually
expects, so you don't have to write the output by hand.

IIUC there can only be one vga device, so this seems correct.

I will check to see what the status was. I have only tested it down to
5.0, but did have earlier versions in my patch before I sent it.

Well it does work, so I guess it does! But I will do as you say and
make sure all thest tests are working.
