as far as i'm concerned x86 is obsolete: my main devel and testboxes are 64-bit throughout, and i develop for 64-bit by default.
Nevertheless for hard-to-debug bugs i prefer if they can be reproduced and debugged on 32-bit too, because x86_64 debugging is still quite a PITA and wastes alot of time: for example it has no support for exact kernel stacktraces. Also, the printout of the backtrace is butt-ugly and as un-ergonomic to the human eye as it gets - who came up with that "two-maybe-one function entries per-line" nonsense? [Whoever did it he never had to look at (and make sense of) hundreds of stacktraces in a row.]
Also, the majority of kernel bugs still get reported on 32-bit and most of the testers are on 32-bit. So x86_64 is nice but it still needs some work, mainly in terms of debuggability.
