In rough priority order:

- Fix the Composite hook.
- Inject SGI 1600SW modelines directly into mode table when detected
- Get the DRM driver more-or-less written.
  - UploadToScreen through DMA
  - XV acceleration using one of the memory windows
  - DownloadFromScreen using the other memory window
  - Optionally, UTS through a memory window for non-AGP case
- Various performance errata from the docs
- DRI driver

Open issues:

Would using the DLP within the server help?  It might, if only for the easy
"wait for vblank" feature (flag it for the first command in the timeslice...)

DLP might be able to use a display list in AGP space... but, uh, how.

DLP for 3d, however, makes tons of sense.
