bluesleep.c does seem really out-dated.. since then the linux PM has changed and android also has this suspend/resume .. which I don't think bluesleep will help out in. one more thing to note is ... what are the interfaces that your bluetooth chip has to the apps processor ? is it just uart? or is there a wake up line. which needs to be configured ?
we had similar problems when we saved and restored the contexts of the uart, certain uart registers were left out and hence uart would stop working after suspend/resume. there might also be the problem of the gpio glitch which would reset the chip. so have a look at all the h/w interfaces your chip has with the apps processor.
