I got a new motherboard for my home server, it is a Super Socket 7
Gigabyte GA-5AA rev 3.2, it has an UDMA 66 connector and it has SDRAM
and a p233MMX. The problem: I boot 2.8, I see on dmesg:

pciide0 at pci0 dev 15 function 0 "Acer Labs M5229 UDMA IDE" rev 0xc2:
DMA (unsupported), channel 0 configured to compatibility, channel 1
configured to compatibility
pciide0: channel 0 interrupting at irq 14
wd0 at pciide0 channel 0 drive 0: <QUANTUM FIREBALL KA9.1>
wd0: can use 16 bit, PIO mode 4
wd0: 16-sector PIO, LBA, 8809MB, 16383 cyl...

This hard drive (KA9.1) is UDMA66 native. So the problem seems to come
from an unsupported ide chipset, am I right ? Is there something I could
do ? Would there be a kernel patch for that chipset now ? Is it my box
that is screwed or really the kernel ? I was hoping to have some much
better IO with that motherboard (compared to my old where I was on PIO
all da way), that's why I bought it !! I can't stay on PIO, impossible,
and don't wanna switch to linux only cuz it supports it... help !
