I've tried to reproduce this issue under GA-965P-DQ6.
JMB363 works fine in 2.6.22-rc2.
The dmesg log is attached.
It will not show any device name in pata_jmicron.

If you disabled the entire old-IDE driver, this message should not be
existed.
It should be like this:

ACPI: PCI Interrupt 0000:03:00.1[B] -> GSI 18 (level, low) -> IRQ 19
PCI: Setting latency timer of device 0000:03:00.1 to 64

scsi7 : pata_jmicron

ata8: PATA max UDMA/100 cmd 0x0001a800 ctl 0x0001ac02 bmdma 0x0001b008 irq
0
