SVN rev 198582 on 2009-10-29 13:27:14Z by nwhitehorn
Turn off use of ATA_A_4BIT on modern hardware. This flag was already
obsoleted in 1996 by ATA-2, and crashes some modern hardware like some
revisions of the Serverworks K2 SATA controller. Even very ancient
hardware seems not to require it. In the unlikely event this causes
problems, the previous behavior can be re-enabled by defining
ATA_LEGACY_SUPPORT at the top of this file.
