in my case I don't have exactly the same lines in dmesg,

my JMicron JMB363/368 seems to have a different design, it's not exactly
identical to JMB363 SATA/IDE Controller, in dmesg I can read this :

dmesg | grep micron

[ 0.860659] pata_jmicron 0000:03:00.1: enabling device (0000 -> 0001)
[ 0.866760] scsi0 : pata_jmicron
[ 0.870045] scsi1 : pata_jmicron

lspci :

lspci | grep JMicron

03:00.0 SATA controller: JMicron Technology Corp. JMB363 SATA/IDE
Controller (rev 10)
03:00.1 IDE interface: JMicron Technology Corp. JMB368 IDE controller
(rev 10)
