Log Message:
humble beginnings of FX5/10 support. This will:
- provide a working, accelerated console at least on my FX5
- ROPs and alpha blending don't work, so we use a putchar() based cursor()
  and disable alpha fonts
- X11 can use a hw cursor and 24bit framebuffer, but since we don't know how
  attributes work (yet) this will give us the blue channel piped through the
  8bit palette. With a linear ramp that's at least somewhat usable.
Next steps:
- provide an 8bit fb with palette so we can run X in colour
- find the FX5's equivalent of the VISFX_FATTR register so we can either force
  24bit colour or use proper WIDs
