We've had some HP machines with this behaviour. The trick on them was to boot with:
hda=noprobe hdc=noprobe
and the disk shows up as sda instead of hda, now working at full speed.
This has to be done during installation and manually added to grub.conf after the installation.
That did the trick. The machine is now about ten times faster.
Thanks very much, you saved my day!
