i just checked it: commented out the passage of the commit in kernel 
2.6.24-rc7-git4 and compiled it: wol WORKS. so this one line is causing 
my wol-disturbance...


but i noticed another "bug" on 2.6.24-rc7-git with sky2: dmesg shows a 
lot of lines every 5 seconds:

[...]
[  357.400462] sky2 0000:02:00.0: error interrupt status=0xc0000000
[  362.442039] printk: 41 messages suppressed.
[  362.442043] sky2 0000:02:00.0: error interrupt status=0x80000000
[  367.439151] printk: 18 messages suppressed.
[  367.439156] sky2 0000:02:00.0: error interrupt status=0x80000000
[  372.436267] printk: 30 messages suppressed.
[  372.436271] sky2 0000:02:00.0: error interrupt status=0x80000000
[  377.350236] printk: 19 messages suppressed.
[...]

since i do not notice any errors (yet) i'll wait till next rc, maybe it 
will be gone then...

but i'm happy wol works again on 2.6.24 :)
