Please do not post your response on top.

What I was thinking about is the delay variable:

1056 static struct fb_deferred_io broadsheetfb_defio = {
1057         .delay          = HZ/4,
1058         .deferred_io    = broadsheetfb_dpy_deferred_io,
1059 };
1060 


Try changing that to a higher number and seeing if that fixes your
problem. If so, you and I can work on a patch that sets a parameter
for this.
