OK. I am narrowing this down.
vga_hasmode(G320x240x256) returns true.
But when I use the following code, it seems that I get both horizontal and
vertical scrolling.
I am using the VESA driver. G320x200x256 and G640x480x256 work just fine.
Any ideas?

#include <stdlib.h>
#include <vga.h>
int main(void)
{
int i;
vga_init();
if(!vga_hasmode(G320x240x256))
{
printf("Mode not supported.\n");
return 1;
}
vga_setmode(G320x240x256);
vga_setpalette(100, 63, 0, 0);
vga_setcolor(100);
for(i=0;i<200;i++)
vga_drawline(0,i,200,i);
sleep(3);
vga_setmode(TEXT);
return 0;
}
