I'd imagine ATI wouldn't let that slip by them, although I would be wary of performance issues. Definitely check benchmarks before delving. But Like I said, I'm pretty sure ATI will ensure Crossfire compatibility.

256 bus where ?

There will never be a 256bit bus on a 5770, they may stick a 256bit bus on a juniper chip down the line however a change like that means a new card and name EG 5790, it would never be sold under the same 5770 name since it'll cost more and out perform it
Personally I think we will see a 5830 type card with disabled shaders LONG before we see a redesign on the 5700 series cards (if we ever do see a redesign) to stick a 256bit bus on it, remember it costs money to redesign the chip, and a bigger bus = bigger chip = costs more to make, as well as the bigger the chip the more chance of a defect on it during manufacturing since TSMC's 40nm wafers = ****, thus driving costs up more so chances are unlikely its worth while to do anyway
where as to make a 5830 type card you just disable shaders and lower the clocks, they would already have 5800 GPU's that have defective shaders, or arent stable at 5850/5870 clocks because of the 40nm manufacturing problems at TSMC
