it is interesting to see this feature/demo

especially as i recently found that S3 will/has been removed and S0ix will replace it

Suspend/wake-up would be awesome..especially after x mins of inactivity <3
Though, tinycore (re)boots quite fast..what about auto-hybernate? (afaik they are two different strategies).

I don't fully get the vc4-suspend though, its kernelcode AND some flashing is required?

cool find though!

ps. I see what you did there ('the suspense is over')
