Not sure if this helps, but I have booted an Acer Aspire One off of an Ubuntu 
8.10 live USB key.  I think I used wired ethernet like that,
but I'm not 100% sure.  So possibly a newer kernel would help you.  Perhaps 
Ubuntu 8.10 or K12Linux.  I'd try K12Linux, since it sounds
like it's pretty easy to test LTSP with that distro using the live cd.
