Many third-party vendors are just/still getting their stuff working on 64-bit, so, sadly, no. The poor saps who have to run non-free software, especially.

But things are much better today than they were even just a year ago, and these are future discussions. It seems likely that a year hence everybody [for most values of 'every'] will be up to speed, which is about when F11 will be EOL.

My brand new eeePC 1000he is only a 32-bit Atom, though, so as much as I'd like to support old gear, I'd like it to be fast on my netbook too. But I agree with the statisticians in the room who are calling for data.

One thing that might seem counter-intuitive is that people tune for old hardware as well as new. I have a project on a Via C7 that I run a gentoo-based distro on because I can tweak compilation for that hardware, and I've seen 40% gains in some areas. On a Core2Quad, I run Fedora and don't look back, as I have CPU to spare and haven't seen a benefit in tuning for it.
