For anyone who has a VIA or an nVidia nForce3 IDE controller (common on some
of the new Athlon[64] boards): can you perhaps try:

	1) updating your kernel sources
	2) applying the following patch
	3) booting the resulting kernel

..and see if your IDE controller is still properly supported, or
is now properly supported? Reports about older VIA PCI IDE controllers
are also welcome.

The patch makes viaide match the nVidia nForce3 chip (should be no
problem there), and also scans the whole PCI bus the controller
is on, to find the PCI-ISA bridge for VIA IDE controllers. Those
can only be properly identified if you know the ID of that bridge.
