No, because there is no onboard framebuffer in the SS20 (or SS10BSX).
The cg14 VSIMM is actually the entire framebuffer (video memory and
ramdac) on a plug-in card.  The SX is not a frame buffer, it's only
the imaging accelerator built into the memory controller.  It can only
twiddle bits in memory, it can't display them.
