Best way to find out is to try it, you may find out that e.g., these
parts are now
accelerated or that they are so infrequently executed that you don't
really care.

Well, afaik the way the support is implemented is by replacing at least part of
the windows / linux gfx stack (details depend on the product). So, win98 has
different versions of gfx APIs that need replacement and since there
is "no market"
nobody cares to write this code.

OTOH, qemu is open-source software so nobody is going to stop you from
scratching
your itch if you are skilled and want / need win98 accelerated graphics.

Probably this is a moot point since there is no (obvious) way to pull
off such a trick
as porting a complex piece of system software like qemu to a stream computer.

OTOH, the emulation of some of qemu's "virtual peripherals" might be
possible to speed up,
or the underlying OS could be speeded up in ways that might benefit qemu.
But before any of this happens, gpgpu would need to become more "mainstream"
and expose a standard cross-vendor API.
