Do laptop video cards die?

[david-8uUts6sDVDvs2Lz0fTdYFQ at public.gmane.org (David Kramer)]

SO I went over to my laptop a few hours ago, and the screen was blank 
and unresponsive.  That usually means my last interaction was on the 
second screen (on my TV with DB15 input), so I blindly type in the 
password, and nothing.
Turn on the TV, and no signal.
C-A-Backspace, and nothing.
C-A-Del, and nothing.
Hard power down (hold down power button for 4 seconds)
Power up again, and nothing on screen.  Not even during BIOS or GRUB.
Panic excessively, and nothing.

However, being Linux, I try to ssh in from another box, and a small tear 
of joy trickles down my cheek.  I start backing up the entire laptop to 
an external USB hard drive (still going).

I noticed the following in Xorg.o.log:

So I'm pretty sure I'm totally screwed, but I want to bounce my 
assumptions off you to see if they're panic-derived or reality-derived

The problem is most likely the video card and not the LCD panel or 
backlight, because:
- I don't see anything on BIOS or GRUB
- I don't see anything on the TV when connected to the external monitor 
jack (and I tried another regular LCD monitor, too).

There's a place close to me (Waltham) in Newton called CTS computers.  I 
used to buy a lot of stuff there back when I built my own frankenboxes a 
few times a year, but I don't know if they do laptops.  Any other 
suggestions near Waltham?

Thanks.
