Same for my Inspiron 4150 (also ATI Rage 128 Mobility MF).

One other note, the screen does go blank in Windows XP also.  Even if
I set the BIOS (rev A05) to disable it when plugged in.  It sometimes
takes a day or two for it to get in this mode, but once there, it
always blanks after a few minutes.  Moving the mouse, pressing keys,
etc do nothing to refresh the screen.  I can login remotely, and
key presses are responded to (I can reboot the machine as long as
was in an xterm), but I just can't see what I'm doing.  When it's
real bad, the screen will blank while I'm using it and sometimes
every minute or so.  The only way to get it back is Fn + F5 then
Escape out of the menu.

I do get the white screen every now and then also, when
suspending and resuming.  But I think the blank screen is
a BIOS bug.
