Hmm, I just plopped in a 20267 here and it works perfectly:
PDC20267: IDE controller at PCI slot 00:0c.0
PDC20267: chipset revision 2
PDC20267: not 100% native mode: will probe irqs later
PDC20267: (U)DMA Burst Bit ENABLED Primary PCI Mode Secondary PCI Mode.
ide2: BM-DMA at 0xa000-0xa007, BIOS settings: hde:DMA, hdf:pio
ide3: BM-DMA at 0xa008-0xa00f, BIOS settings: hdg:pio, hdh:DMA
hde: IBM-DTLA-307030, ATA DISK drive
ide2 at 0xb400-0xb407,0xb002 on irq 16
hde: host protected area => 1
hde: 60036480 sectors (30739 MB) w/1916KiB Cache, CHS=59560/16/63,
UDMA(100)
hde: hde1 hde2 < hde5 >

Can you please send me the config settings?

That's expected.
