I get (without grep, just lspci):
82845G/GL[Brookdale-G]/GE chipset integrated graphics device (rev01)
I would suggest browsing this page
, it explains a lot about your card and its configuration.
your card would be classed as a 845G or 845GL.
for its initial set up I would suggest the following
Boot in to run level 3 again (kernel option - default - add a "3" w/o quotation marks)
log in as your a user or guest if a livecd
su to root
type XFdrake (note the case sensitvity)
choose your monitors resolution
choose 15 or 16 bpp (not 24)
accept those choices
then type "xinit draklive-install" if all has worked this will load up the installer only
once installed use run-level 3 to set up your network connection (via drakconnect)
you will need to do a full update (via apt) and install an alternate window manger ( I would suggest icewm)
once installed restart the system and change the session to icewm.
