We do specifically blacklist a few adapters to vesa instead of nouveau, ones which have been reported to fail completely with nouveau. What's the PCI ID of your graphics card, please? lspci -nn will tell you. --
nVidia C51 [Geforce 6150 Go] [10de:0244] (rev a2)
My card has a problem with nouveau either on F10 or F11 except for suspend/resume (as expected)
