I have succesfully flashed my MS25 with the new firmware a few weeks ago, and after that I was wondering about how could we play with the drive a little bit more... maybe it sounds stupid, but I'm not an expert, so take it as an idea or sort of:
what if we could prevent the 360 from getting back to the dashboard after ejecting the disc? in other words, can we make the 360 think (with a firmware mod) that the disc is still in the drive, nothing's changed, so it would try to continue the game? I know that if there's nothing in the drive, than there's nothing to read, but maybe we could get the 360 in a state that was never found before... most likely it would lock up immediately, but who knows...
maybe the above can be done with a firmware, I don't know, but I will try and disconnect the SATA cable during a game, next time I open up the 360, just to see what happens
