* Fixed LBA48 access in the ide_adapter. This should fix bug #2700 and probably
  others as well: accessing data beyond the 128 GB barrier on PATA hard drives
  did not work and could potentially screw the first blocks of your hard drive.
* Also fixed queued LBA48 access in the IDE bus manager (this has already been
  removed in the ATA bus manager).
* Whitespace cleanup.
