some problems for my Dell Inspirion 6400 Core 2 Duo / ATI x1400 / 1 gb ram
1) fglrx - works (3d not tested - I don't need it)
2) SMP - not working

tested - encoded video with x264 (compiled to be 64 bit) and comsol multyphisics - made some example calculations (package was installed in x86_64 mode)
3) there is package manager gui frontend - no new or other packages in original repos.

4) tried to install crossover office (did successfully in Bluewhite64) - failed (some pakages with 32 emulation are missing)
5) tried to compile avidemux (failed, to many dependencies to install - I didn't have that much time)
overall:
starts and works fast, faster then Archlinux, Frugalware and Bluewhite64 (due to default xfce4 desktop, I worked in GNOME and KDE there)
misses package repo, I would like to use BW64 one (it is quite big)
I wanna stay in it if I'll get CrossOver and Avidemux, but now back to arch_i686, waiting for stable release or something like packages of vlc, avidemux ... also OOO (I've tried to use i568 and BW64 builds but failed), OOO should be as an option because some people (like me) use it almost every day...
