I reverted this patch and ide-mm-ide-make-ide_hwifs-static.patch (for compile breakage reasons). It's better but still fails to find the IDE device. What is better is that it finds ide0 at; ide0 at 0x1f0-0x1f7,0x3f6 on irq 14 but does not identify any of the disks nor does it find ide1. For comparison, a "good" dmesg looks like [ 1.793244] Probing IDE interface ide0... [ 2.235292] hda: IBM-DJSA-220, ATA DISK drive [ 2.915457] Probing IDE interface ide1...
