By the way, I am now using:
options        VESAFB_WIDTH=1024 
options        VESAFB_HEIGHT=768 
options        VESAFB_DEPTH=16

And the kernel said:

  vesafb0: fb 1024x768x16 @0xd8000000

The text console had many more lines, but readable and usable. And X looks 
great to me. The Xorg vesa and vga drivers do not work for me. I'd rather 
use this than "via" aka openchrome aka unichrome. (Thank you jmcneill!)

Also by using these new width, height, and depth settings, when I exit X, 
my console colors are correct. Before with the defaults, my console 
X logs had:

(EE) wsfb(0): error saving colormap Invalid argument
(==) wsfb(0): Backing store disabled

The first error is from the Xorg's wsfb_driver.c:

        if (ioctl(fPtr->fd, WSDISPLAYIO_GETCMAP,
                  &(fPtr->saved_cmap)) == -1) {
                xf86DrvMsg(pScrn->scrnIndex, X_ERROR,
                           "error saving colormap %s\n", strerror(errno));

I see that vesafb does support WSDISPLAYIO_GETCMAP, but I don't know the 
problem here. The other ioctl errors above are also from the Xorg wsfb 
driver code.

Also, does anyone know how I can get Xorg to stop probing my PCI and 
buses? The xf86Init.c doesn't seem to have any options for skipping the 

Is this probing even needed if I am using wsfb with wsdisplay on vesafb?
