Comment # 8 on bug 1143148 from Robert Krawitz

Interestingly enough, it works fine on my old laptop (hwinfo attached, it's a
Core i7-920XM) with either the 15.0 or 15.1 kernel.  I never tried it with 15.0
on the system I filed this bug on; it's a rather new system and I hadn't tried
to scan on it prior to upgrading to 15.1.
