Well it's an ATI chipset, so well, not surprising.  There was some
recent patches on the kernel mailing list dealing with SATA issues on
the SB600.  I don't remember if they are in 2.6.20 or will go in 2.6.21.

Usually having to set the bios to anything other than native
SATA/enhanced/whatever they call the setting that does no emulation, is
not a good sign of having the right working drivers.

I think the debian kernel team has experimental 2.6.20 kernel packages
that you could try to see if it is any better.
