BTW, I would guess that scrolling is slow in this driver.  Since

this driver

can do pan_display, If this: 

info->flags = FBINFO_DEFAULT | FBINFO_HWACCEL_YPAN;

is added somewhere before register_framebuffer(), and

var->xres_virtual >

var->xres, you might get a several-fold increase in scrolling speed

(since

scrolling mode will be SCROLL_PAN_REDRAW instead of SCROLL_REDRAW).

Err, afaict, it is already added before register_framebuffer():

	info->fbops = &s1d13xxxfb_fbops;
	info->flags = FBINFO_DEFAULT | FBINFO_HWACCEL_YPAN;
	
[snip]

	if (register_framebuffer(info) < 0) {

The scrolling doesn't feel particularly slow here... Though it's hard
to tell in 640x480 ;)

Thanks
