Most of the issues in running a Linux distro on a netbook stem from the kernel that is used (and X autodetection).
Netbooks are more and more supported with recent kernels, and you can expect the latest VL 6 to run much better than VL 5.9.
I haven't tried the latest release candidate yet on a netbook, but you should expect wireless and wired, hibernate functions, and screen resolution to be working out of the box... and that should apply to a lot of distros, not specifically VL.
That said, there will always be some issues like special keys, customised scripts, and connecting to an external monitor that might require extra stuff not in the default distro.
These could be handled by having a package in the repo that installed the relevant stuff, so I don't see the big deal.
It makes much more sense (I think) to have this package in the repositories than to produce a VL version specifically for the EEE. A new VL version would require a lot of work and a lot of testers. I find that a bit silly, when the majority of people don't have netbooks (at least, not on this forum). Plus, the eee isn't the only netbook on the market and not even the one that has been sold the most. Finally, there are different models of the EEE.... surely, you don't mean to suggest that the VL crew release (and support) a whole distro just for a single computer model. If someone is up for it, great... that's what open-source is all about. But given the limited resources, you should appreciate that it makes more sense to focus on a general distribution.
In the end, we do what we can. I have made an effort to get VL 5.9 running properly on an aspire one, documented the steps on a thread, and will do the same for VL6, possibly creating a package for the aspire one.
Feel free to do the same with the EEE.
