No, it shows up as;
00:01.0 VGA compatible controller: Intel Corp. 82810E DC-133 CGC [Chipset
Graphics Controller] (rev 03)

I think your talking about an X problem right? I'm just trying to do a
console framebuffer with the i810fb driver.

But as for why you would maybe having problems with X on a Dell with that
chipset.... Check into your logs and see if it is having a problem
allocating video memory. Dell has this habit of breaking intel firmware by
changing the I/O address for shadow memory allocation after they recieve
working boards from their manufacturers. So what could be happening to you
is when X tries to allocate the shared memory, it hits intels normal I/O
address, finds nothing there and gives up with about 1 meg of memory to
use which pretty much gives you 640x480 at 24bpp. You can try setting it
to 16pbb and 800x600, or 8bpp at 1024x768 and see if it give you the
resolution your after. (and that will tell you if you have a dell
hacked/broken intel firmware)

If that is the case (like you have something like a Inspiron 1100, 5100,
m500. you didn't specify or I could better help you) A workaround for X
has been committed to both branches (xorg and xfree86) about a year ago.
So FC2T1 might already include it... But it is specific to the Dell model.
