Uhm, tho following is with 2.4.19-xfs:

PDC20268: IDE controller on PCI bus 00 dev 98
PDC20268: chipset revision 1
PDC20268: not 100% native mode: will probe irqs later
PDC20268: (U)DMA Burst Bit DISABLED Primary PCI Mode Secondary PCI Mode.
    ide2: BM-DMA at 0xfce0-0xfce7, BIOS settings: hde:pio, hdf:pio
    ide3: BM-DMA at 0xfce8-0xfcef, BIOS settings: hdg:pio, hdh:pio
hde: Maxtor 4D080H4, ATA DISK drive
hdg: Maxtor 4G120J6, ATA DISK drive
ide2 at 0xfcc8-0xfccf,0xfcda on irq 10
ide3 at 0xfcd0-0xfcd7,0xfcde on irq 10
hde: 160086528 sectors (81964 MB) w/2048KiB Cache, CHS=9964/255/63, UDMA(100)
hdg: 240121728 sectors (122942 MB) w/2048KiB Cache, CHS=14946/255/63, UDMA(100)

So there *is* UDMA 100 support...

Cheers,
Juri
