Subject: [PATCH] ide-generic: jmicron fix
Some people find their Jmicron pata port reports its disabled even
though it has devices on it and was boot probed. Fix this
(Candidate for 2.6.18.*, less so for 2.6.19 as we've got a proper
jmicron driver on the merge for that to replace ide-generic support)
