I'm using the standard Jaunty (not NBR) in a 1008ha and it
works very well. You need to make wired and wireless networks
work (see howto in other posts of mine). Furthermore, if you
may want to improve the graphic performance by following
the "Intel jaunty graphics performance guide", because these
netbooks have the Intel 965 chipset and, thus, the graphics
performance are not very good in Jaunty. I've done fixed,
upgraded the kernel, and now I'm running compiz (with DRI2),
perfectly.
