The Xfree configuration can't handle a 1280x1024 at 32bits at 85hz, even at 16bits, the strange thing is if i choose more than one configuration and test them the program crashes (not the entire installation program), and i can only choose one resolution at a time. If i select 1024x768 or 1152s i can't have a graphical login, only with 1280x1024 (but on a 19" with a rex of 89hz interlaced isn't the optimum...) or 1600x1200 i can give it.
This should be fixed in 6.2
