I don't understand, but in the graphic instalation, I choosed 3 itens to config the keyboard: type, abnt-2; layout, brazilian; language, portuguese. And I had tested it on the kbrd test's field on the same screem, ok, everthig was fine, but when the instalation finishes and the computer rebooted, the kbrd wasn't working as the same on the instalation, is worked like a US... So I ran "kbdconfig" and choosed again br-abnt2, so, it almost worked fine, some keys as "?" simple didn't worked again, so I compared the kmap with others distributions where the kbrd worked fine and I saw that yours kmap is bad... So take a look at Conectiva, here in Brazil, they have a good kmap... So I'm using their kmap instead of your... Thanks.
The keymap seems have been fixed in the current release (8.0).
