scrollmode, accel_flags, fbcon.c ...

are scrollmode or accel_flags meaningful to anyone here?

Paging through fbcon.c, I've realized why the radeonfb driver is still 
slow -- the accelerated functions are never being called!  

Hardwiring scrollmode to __SCROLL_YMOVE in updatescrollmode() makes my 
console go a lot faster :)

So within fbcon.c why is there a "scrollmode" variable which can be set
to:  __SCROLL_YWRAP, __SCROLL_YPAN, __SCROLL_YREDRAW, or __SCROLL_YMOVE?

Also accel_flags actually useful to anyone?  I see in the fb code some
half-hearted attempts to test for FB_ACCELF_TEXT, but it's not clear at
all to me where these accel flags are supposed to be set... are they even
relevant with the new accel interface?  It seems all this is properly
replaced by filling in the fbops to either the driver's custom fillrect()
or cfb_fillrect(), no?
