2.6.28-stable review patch. If anyone has any objections, please let us know.

From: Alan Stern <stern@rowland.harvard.edu>

commit 5126a2674ddac0804450f59da25a058cca629d38 upstream.

This patch (as1219) adds the IGNORE_RESIDUE flag to the unusual_devs
entries for Genesys Logic's USB-IDE adapter. Although this device
usually gets the residue correct, there is one command crucial to the
operation of CD and DVD drives which it messes up.
