ATAng suspend/resume support broken

With today's ATAng, I can suspend my laptop but when I resume, the system
hangs.  I'll try to get the exact dmesg with a serial console since
syscons gets screwed up by resuming (this is normal behavior).  In any
case, my laptop hangs with the drive light on while trying to reset the
ata controller.  I can't enter DDB.  By reverting just the ATAng commit to
2003/08/23, suspend and resume work well.  Here is my dmesg from a working
suspend/resume...
