Newest kernels should now have workarounds in it (2.6.27 should also
have it backported - but not for 2.6.26 (I think)). The problem was,
that several devices report invalid sector count (1 more then there is)
and that causes problems, when attempt is made to read last sector.
Newest kernels have workaround for all Nikon, Pentax, Nokia and Motorola
devices. I'm also including entire message text about adding update to
2.6.27 tree. But udev change helped to work around it in existing system.

commit 506e9469833c66ed6bb9acd902e208f7301b6adb upstream.
This patch (as1202) adds Pentax to usb-storage's list of bad vendors
whose devices always need the CAPACITY_HEURISTICS flag. This is in
addition to the existing entries: Nokia, Nikon, and Motorola.
