I have done some debugging, and here are the not-so-exciting results:

GPE08 is dispatched. My debug shows something like this:

* Is a control method
* Method at AML address d08047a4 length 39D
* Begin method parse Entry=cff43904 obj=cff4238c
* State=cff4ec00
* Completed one call  to walk loop, AE_OK, state=cff4ec00
* Parser exiting, status AE_OK
* Begin method execution Entry=cff43904 obj=cff4238c
* State=cff4ec00
* Completed one call to walk loop, AE_CTRL_TRANSFER State=cff4ec00
* Execute Method 00000000, current state cff4ec00
* State=cff4e800
* Completed one call to walk loop, AE_OK, State=cff4e800
* Parser exiting, status AE_OK
* Starting nested execution, newstate=cff4e800
* Completed one call to walk loop, AE_OK, state=cff4e800
* Completed one call to walk loop, AE_OK, state=cff4ec00
* Parser exiting, status AE_OK

And keeps doing this every time GPE08 is enabled.

Any ideas ? Right now I have disabled the GPE and can trigger an enable 
via /proc, so if you need more info, please tell me.

The hex dump at 0xd08047a4 + 1 shows something like:

5c 2f 04 5f 53 42 5f 50 43 49 30 50 43 49 42 42 52 47 42 60 79 60 0a 18 
60 0c 0b b1 20 00 60 70 0a af
5c 2f 03 5f 53 42 5f 4d 45 4d 5f 49 45 44 49 53 4d 42 52 0b 00 ff 60 0a 
00 0a 00 0a b2 a2 4b 35 91
5c 2f 03 5f 53 42 5f 4d 45 4d 5f 47 50 35 30 91
....

And now a stupid question: on the second line I believe it reads as 
"Root" "Multiname" "3 Segments", but it looks like it has 4 
(_SB_.MEM_.IEDI.SMBR). Is this correct ?
