Bug#623363: "git bisect" debian sources?

[CSights <csights@fastmail.fm>]

Hi,
	Is there a way to do the equivalent of "git bisect" the debian kernel 
sources?
    My computer no longer hibernates and resumes with debian 2.6.38, but this 
was possible with debian 2.6.32 .
	The vanilla 2.6.33 does write to disk correctly, but then doesn't resume.  
(Blank screen after reading image from disk.)

Thanks,
	C.
