See my recent posts re: A8N-VM CSM with the same issue. The DSDT table is so 
fundamentally broken (but has a correct checksum, so it's not an issue of one 
nibble falling over during manufacturing) that you can't use it on anything 
except Windows (which ignores the AML spec saying that names consist of 
characters A-Z and _). In any case, what I did to fix this was:

1) Boot 6.0-R x86 in ACPI disabled mode
2) Use acpidump to get the DSDT
3) Hex edit the DSDT (you can't disassemlble it because it's so broken)
4) Set that modified DSDT for use as per Handbook section 11.rumtiddlypo
5) Reboot into 6.0-R x86 with ACPI
6) Profit!

It seems to be a speedy and stable machine from there on in, at least when 
doing only one thing (portinstall kde) at a time.

If you like, I can post the modified DSDT on a website somewhere.

Also with the fixed DSDT, ata-33. nForce430 is still too leading-edge. Do you 
get the nForce430 NIC listed at all? Mine doesn't even show up in pciconf 
-lv.

I figured that the first BIOS update (to 0506) would fix the problem, but no. 
What's worse, it also made the machine lock up in x86 no-ACPI mode.
