For the framebuffer drivers that may not work. For a trident card I use tridentfb.mode_option=1280x1024@60. The options for the different drivers can be found on the kernel documentation on Documentation/fb. What worked best for me with nouveau on recent kernels is to disable all framebuffer drivers and enable CONFIG_DRM_FBDEV_EMULATION. It will boot into the framebuffer without flicker. You can also use the VESA driver to boot and then load the nouveau module (which udev should do automatically for you). For me this switches to the fb console as soon as the module loads but it gives me a blank screen or a panic if any other fb drivers than VESA are builtin or loaded.
