Today I am testing with a self compiled kernel with boot delay support compiled in.
I booted the kernel with the kernel parameters added: earlyprintk=vga boot_delay=1000
Then I watched the lines coming up one by one during boot and watched the WLAN-LED:
{{{
bio: create slab <bio-0> at 0
}}}
Then the WLAN-LED gone off.
{{{
ACPI: Interpreter enabled.
}}}
Thus It seems that the WLAN-LED turns off during ACPI initialization.
