I've left it once for a while, but I'll test for how long and report back,
seems to me it was about 4min.

Thanx, got it!

Well, if it was recommended I haven't saw that recommendation anywhere. Used to
build an intel driver into kernel image itself, KMS kicks in as early as
possible. I did the same with radeon, and it works for me great this whole
time.

Don't mean to be rude or anything, but I don't know if it is recommended (or
desirable) to commit a piece of code to mainline that will _require_ a blob
that can't be found in linux-firmware ?

I'll see about the timeout and report back in. 

Thanks Michel
