The problem is not enough memory for all the colors and pixels in that VGA mode.
It seems to me that a 512x384 bitmap with one bit per pixel WOULD barely fit in 24K of HUB RAM.
In that case would the Graphics driver just not be able to handle it?
The original Macintosh had a black & white display of 512x384. This resolution is not bad for line graphics, and, as stated, only takes 24KB of RAM. By rendering this display as 1024x768 using 2x2 pixels per bit, this maps perfectly to a 1024x768 LCD monitor.
You could build a double-buffered 512x384 vector display out of two Propeller chips. They could take line-drawing commands and even render 3D lines. It would be good for live data visualization or vector-based video games.
