regarding suspend:

I already sorted this out - the problem was in wl driver (the wi-fi driver,
which is actually open source, but for some reason not implemented in kernel,
so it needs to be installed as 3rd / proprietary driver).

I am unloading this driver before suspending, so it works now to me. Seems to
be problem with wl, not a kernel.

Regarding brightness, it still doesn't work - eg. the keys which are supposed
to change the brightness do not respond and there are 2 backlight controls in
/sys/class one is defunct and one is OK
