to have 3d acceleration for intel cards you will need
1) intel agpgart, drm and respective drivers (i am not sure which ones
you will need for this card - maybe i810, i830 or i915) compiled in your
kernel or as modules. if you compile them as modules the system will
choose the right one.
maybe these are already present. what is the output of lsmod?
excerpts from my config (i knew which things are needed, so i compiled
it to the kernel)
CONFIG_AGP=y
CONFIG_AGP_INTEL=y
CONFIG_DRM=y
CONFIG_DRM_I915=y
2) i810 module for xorg version 7.0; for older versions i think it is
automatically installed
3) to get acceleration working you might need the newest dri drivers. if
your card 3d capabilities aren't recognized (you will see it in the xorg
output) download the latest dri from dri.freedesktop.org - you will need
i915 driver, i think - search the archive of debian-user, this was
surely discussed relatively recently
one comment - you need xorg i810 driver and dri i915 driver
4) modify your xorg.conf accordingly - relevant parts of my xorg.conf
are displayed below.

there can be one more issue with laptop - if you have widescreen panel,
you may have problems with setting the proper resolution. in such a
case, use 915resolution available from debian packages.
hope i didn't forget anything important. regards,
