DSDT problems with Asus K8V-X SE

Hello,

I'm not sure if this is the right mailing list to post DSDT problems to, but someone said acpi-devel
at sf.net and when I found that it directed here.

My problem is a broken DSDT, I have tried to fix it, but I don't know if I did it the right way, nor
how to solve the warning that remains when the errors are gone.

http://rage.kuonet.org/~anmaster/acpi/dsdt.dsl.pre-fix is the one I get when decompiling.
http://rage.kuonet.org/~anmaster/acpi/dsdt.dsl.fix is the my try at fixing it.

The errors I get with the unfixed DSDT are as below. I want to know if my fix is correct and what to
do about the remaining warning (Not all control paths return a value (STM_)).

The motherboard in question is an Asus K8V-X SE. I found a custom DSDT for "Asus K8V-X SE Delux" but
it didn't work (lock up at boot) for me.

What exactly is broken about your DSDT that requires you to 'fix' it? 

Yes, lots of vendor DSDTs won't compile with the Intel compiler - this is 
because the Microsoft compiler is far more 'generous' than Intel's, and will 
allow a lot of spec breaking rubbish in.

However, the ACPI interpreter in Linux can handle most of these just fine; and 
if it can't, then that's a bug that needs to be fixed in Linux (since Linux 
should be able to handle unmodified MS compiled DSDTs out of the box).

I get lots of lock ups (no kernel oopes or other useful info, just everything locks up) that goes
away when I disable ACPI. Someone on IRC said that I should try to fix the DSDT to see if that helps.
