tmm 10a0c5eb2d - remove some outdated comments
- tweak the announce message a bit
- remove '\n's from a few panic() calls
- don't use the DVMA base adress the firmware reports; instead, figure
  it out from the appropriate register on Sabres and let the IOMMU code
  choose it on Psychos. This also makes the IOMMU TSB size freely
  selectable.
