Thank you for linking this! Wasn't able to find this git repository
for it - only binaries for nonfree operating systems (yuck).

Well, we'll see what I can do with that. :)

Oh wow, yeah, that would be great. Thank you for pointing this out!
Compiling the kernel in 15-20 seconds instead of the current *couple
minutes* would definitely be great.
