I cheat. I've adjusted config.h manually and have put it in 
grub-core/braille. There is a conflict with our own config.h in the 
variables like PACKAGE_NAME but I've just removed PACKAGE_NAME for 
brltty for time being.

What kind of monitoring would you like to have? In GRUB network and usb 
are currently async, rest is sync.

grub_millisleep

That's not currently possible.

Warnings are secondary. We can add -Wno- for brltty.

Fairly easily: copy it to grub-core/braille/brltty and apply the patch.
