Compaq Armada E500: tried to fix dsdt; need a little help

[Sebastian Kemper <Sebastian.Kemper-S0/GAf8tV78@public.gmane.org>]

Hello again,

with the help of a HowTo at Gentoo's forum I was able to fix most of the 
errors. But some remain and I would like you to take a look. I would 
really appreciate it if you read the full story in the Gentoo forum, 
because the formatting is better so you get a better insight in this 
matter and I already fixed many bugs but I'm not sure if my fixes are 
good. So If you would go to 
http://forums.gentoo.org/viewtopic.php?t=122145&postdays=0&postorder=asc&start=27 
I really appreciate it. Thanks!

This is what iasl now says:

The interesting parts in dsdt.dsl look like this:

2159 Method (_PCL, 0, NotSerialized)
2160             {
2161                 If (\_SB.C005.C013.C059.C08A ())
2162                 {
2163                     Store (Package (0x00) {}, Local0)
2164                 }
2165                 Else
2166                 {
2167                     Store (Package (0x01)
2168                         {
2169                             \_SB
2170                         }, Local0)
2171                 }
2172
2173                 Return (Local0)
2174             }

And I don't have a clue what to do here. I tried to change 'Package 
(0x00)' to 'Package (0x02)' and the warnings dissappeared. But I didn't 
know what I was really doing so I reversed my changes.

Another one is this:

dsdt.dsl   735:                 Return (^C08E (Arg0, Arg1, Arg2))
Error    1029 -                             ^ Called method returns no value


I read something about about "Return(Package(0x02){0x00, 0x00})" and 
thought "Hey, I gotta have one of these"

Code:

Method (C08E, 3, NotSerialized)
             {
                 Acquire (^C082, 0xFFFF)
                 Acquire (\_GL, 0xFFFF)
                 ^C08B ()
                 Store (0x07, C05B)
                 Store (Arg0, C05C)
                 Store (Arg1, C05B)
                 Store (Arg2, C05C)
                 ^C08C ()
                 Release (\_GL)
                 Release (^C082)
             }

             Method (C08F, 2, NotSerialized)
             {
                     Return (^C08D (Arg0, Arg1))
             }

             Method (C090, 3, NotSerialized)
             {
                 Return (^C08E (Arg0, Arg1, Arg2))
             }


changed to

Code:

Method (C08E, 3, NotSerialized)
             {
                 Acquire (^C082, 0xFFFF)
                 Acquire (\_GL, 0xFFFF)
                 ^C08B ()
                 Store (0x07, C05B)
                 Store (Arg0, C05C)
                 Store (Arg1, C05B)
                 Store (Arg2, C05C)
                 ^C08C ()
                 Release (\_GL)
                 Release (^C082)
              Return(Package(0x02){0x00, 0x00})
             }

             Method (C08F, 2, NotSerialized)
             {
                     Return (^C08D (Arg0, Arg1))
             }

             Method (C090, 3, NotSerialized)
             {
                 Return (^C08E (Arg0, Arg1, Arg2))
             }

But the writer of the dsdt HowTo at Gentoos forum said this may be not a 
good fix. What do you think?

Thanks

Sebastian
