With this and the following messages the patch for the Impact video
driver will be resubmitted.

- Now - most important - the MUA sends text out unaltered.

- The diff-text is split into several patches, roughly according to
  destinations, although these patches are not all independent. ('hope
  this helps to handle it better :)

- The early-console stuff, probably helpfull only to kernel-debuggers,
  is extracted to an additional patch, waiting backstage for delivery
  on demand (only). (This console in principle is usable from kernel-
  entry on)


This patch brings, yet missing, parts that make a Linux-driven Indigo2
Impact (IP28 and most probably IP22-Impact) an usable desktop-machine
"out of the box".
The driver provides the framebuffer console and an interface for the
Xserver (mmap'ing a DMA-pool to the shadow framebuffer and doing the
necessary cacheflush).
Meanwhile only a few files are affected and obviously no side-effects
to other parts of the kernel are to be expected.

BTW: it would be appreciated, if someone could verify, that this driver
also works for IP22 Impact.
