FWIW, I installed RC4 with the graphical installer and most everything went well and all works. The only issue was with the lilo install step. Granted, this is due to some old issue with the windows partition (second partition on HDD, swap is first), so lilo always gives an error and reports that I should use ignore-table or fix-table. Maybe this should be added somewhere in the lilo config/install screen (with a big disclaimer if selecting fix-table, I guess). Obviously, I ended up booting the installed system via the VL install CD and editing lilo.conf to add ignore-table, then running lilo.
BTW, I just love the new wallpaper!!! And finally the default icon theme is not vista-inspirate....
