note that the current driver exposes a textured xvideo even on r100:

:; xvinfo 
X-Video Extension version 2.2
screen #0
  Adaptor #0: "Radeon Textured Video"
    number of ports: 16
    port base: 63
    operations supported: PutImage 
    supported visuals:
      depth 24, visualID 0x21

et cetera.

(That is from a Radeon Mobility M7 LW [7500].)

The R300+ check seems necessary.

Will everything work right for X over tcp?
