[actualizado] Para futura referência: Xorg.conf
Actualização: descobri o problema do teclado. O layout estava incorrecto - devia ser pt e não pt-PT - e faltava o «Option "XkbOptions" "lv3:ralt_switch"»
Como a NVidia 7025 está a dar problemas com o Xorg, fica aqui um xorg.conf a funcionar em condições com a gráfica, cortesia do Debian Etch. Só falta o teclado, que não está devidamente configurado.
