The fix for the screen blanking bug was not dell or ati specific,
rather it was a general issue:  the wrong crtc was being read in one
function.

I'll try and build you a new binary tonight if I get a chance.  If I
don't get to it tonight and you want to build it yourself, here is the
fix:
in radeon_cursor.c function RADEONLoadCursorARGB().

As you can see all you have to do is change the CRTC to CRTC2.  rebuild
the driver and you are set.

Grab the source from here:
ftp://ftp.xfree86.org/pub/XFree86/4.3.0/source
All you need is the first 3 tar balls.  extract them, make the change
to  xc/programs/Xserver/hw/xfree86/drivers/ati/radeon_cursor.c
then in directory xc type "make World"  

wait for it to build, and then copy
xc/programs/Xserver/hw/xfree86/drivers/ati/radeon_drv.o to your
/usr/X11R6/lib/modules/drivers directory.
