IDE ignores SETXFER failure and for SATA devices SETXFER doesn't really
mean anything (unless it's bridged).  In this case, IDE didn't seem to
be seeing SETXFER failures but the chip being quite weird (SETXFER
failure is associated with the specific device slot not the device
itself.  it's probably a bridge problem.) and from the vendor it's from,
I thought whatever works is okay.

Feel free to re-open bug 8563.  I'd be happy to help. :-)

Thanks.
