cool! I think it would be good if you could file a wishlist bug against sbuild 
("please add support for reproducible building of packages with sbuild") and 
attach the patches there, so they do get lost.

the current setup on jenkins.d.n just uses pbuilder twice. Maybe we should use 
sbuild once and pbuilder once? Could you help us with patches for that too? I 
at least have no clue about sbuild whatsoever ;-) We'd need to use our custom 
repo anyway, so using an sbuild rebuild plus your two patches is rather 
trivial...

git clone ssh://git.debian.org/git/qa/jenkins.debian.net.git and then check 
bin/reproducible_build.sh line 193 and 207 to see how pbuilder is used.

Using sbuild once instead should be trivial, no? ;-)

Thanks for your contribution!
