Dike out support for DEC3000/300* Pelic* and the DEC3000/[4-9]00
Flamingo/Sandpiper families, SLIP, lance Ethernet (especially since `le'
based Alphas are diked out now too), POSIX P1003_1B real-time extentions,
and last but not least "NOBLOCKRANDOM" since the random device is removed.
This lets us fit [barely!]:
