This also fixes the same regression for FireWire.

However, CD burning still fails for me via ide-cd, although in a
different way than without the patch.  (Without the patch, ide-cd also
fails like described by you for SATA.)

With the patch, the failure is as follows.  I don't know if this is
related to the data length arithmetic or something entirely different;
all I learned so far is that 2.6.24 works.  Application log from
2.6.25-rc3 + Tejun's patch + Gentoo's cdrkit-1.1.6 + k3b:
