broken DSDT on sony vaio pcg-grx500

[asu <asubedi-crMJuEk9IMvltQq4i4S/Dg@public.gmane.org>]

Compiling the decompiled DSDT gives me two errors. One error was that
it required ByteAcc access which I fixed easily. The other error is:

dsdt.dsl    16:                 Return (DCST)
Error    1022 -      Object does not exist ^  (DCST)


The region of code it corresponds to is:

DefinitionBlock ("DSDT.aml", "DSDT", 1, "SONY", "B0", 537002772)
{
    Scope (_PR)
    {
        Processor (CPU0, 0x00, 0x00001010, 0x06) {}
        Scope (\_PR.CPU0)
        {
            Method (_CST, 0, NotSerialized)
            {
                Return (DCST)
            }
        }


Changing DCST to _CST and compiling it gives me segmentation fault
while compiling. Realizing that it is dangerous, I tried various
things like DSDT, \_CST, etc. Changing it to 0x0 did not give me any
errors or warnings. Then I changed it to 0x033 which also did not give
me any error. So, I think changing it to 0x0 or 0x033 is incorrect.

I am using iasl-linux-20030918 to compile my dsl file. 

Can anyone point me to the solution to this error?

Thanks,
asubedi
