This sucks. The i860 needs to be enabled, since STIC interrupts get routed
through it. To support the i860 properly, we need a TLB manager and the
right ucode for the damn thing.

Save wscons and the Xserver, this is far as the px driver goes
feature-wise, I think. The limit of non-documentation has been reached :(.
On the bright side, console output works for me with a PXG+ now.
