- Sounds like it. The types are only distinguisable by how they are jumpered
- and the frequency on a crystal to determine the monitor type.

- You need 4.2A or later (4.3 for example), as memory serves.

- No, you don't, if my memory is correct.

- Just appropriate "fb" device entries.

- Note that fewer servers are needed in the future; the multiscreen support
- allows the same server to support many display types. It has taken a release
- or two to qualify the combinatorial display permutations, so you have to
- look at the release notes to figure out what server is for you. In general,
- after the transition is over you'll just have to configure your kernel for
- the device type and a single server will run (on Alpha/OSF, there is only a single
- server, and display types are (in principle at least) dynamically loadable).
