re: PIIX4 controller support on 2.0.x kernels vs 2.2.9

["debian" <debian@mail.fairfax.com.au>]

first an example of boot messages from dmesg output;

Kernel 2.0.34

ide: i82371 PIIX (Triton) on PCI bus 0 function 57
    ide0: BM-DMA at 0xf000-0xf007
    ide1: BM-DMA at 0xf008-0xf00f
hda: Maxtor 90680D4, 6485MB w/256kB Cache, CHS=826/255/63, UDMA
hdc: no response (status = 0xd0)
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
Floppy drive(s): fd0 is 1.44M


Now kernel 2.2.9 dmesg output;

PIIX4: IDE controller on PCI bus 00 dev 39
PIIX4: not 100% native mode: will probe irqs later
    ide0: BM-DMA at 0xf000-0xf007, BIOS settings: hda:DMA, hdb:DMA
    ide1: BM-DMA at 0xf008-0xf00f, BIOS settings: hdc:DMA, hdd:DMA
hda: Maxtor 90680D4, ATA DISK drive
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
hda: Maxtor 90680D4, 6485MB w/256kB Cache, CHS=826/255/63, UDMA
Floppy drive(s): fd0 is 1.44M


How do I get the 2.2.9 kernel to exactly see what my controller is, and I
also have problems with hdc device (ATAPI CDROM) under 2.2.9 (ie not
detected at all)

So strange... any ideas.. I will do more testing when I have time, but so
far I don't see any support directly related to PIIX4 in the 2.2.9 make
menuconfig screens.
