Help with video cards

ok i have a Gateway MT6458 Notebook which has a AMD Turion 64 X2 Mobile Technology TL-50 1.6GHz, 128KB x2 L2 Cache, Hyper Transport technology at up to 1600MHz processor and a ATI Gadeon Xpress 1150M with up to 256 MB of HyperMemory video card and Microsoft Windows Vista Home Premium (lol right off of the box XD)

and i have downloaded SL and when i run it says I do not meet system requirements for my grafics card and it mentions that if i continue they may be problems and brings me to a black login screen but before i can click on the box to but in my login details SL crashes and asks if i want to send a crash report and then closes

also i am running SL in compatability mode for XP service pack 2 and as an administrator yet it still crashes

I did notice that on the bottom of the SL wiki it states that the xpress cards have not been tested and may or may not work

i am also making the assumption that i can play SL not meeting minimum requierements with poor performance but it is another error that makes it crash and not allow me to unless SL crashes when ever it detects that i dont meet minimum requirements but i think it says that because my card has not been tested and therefor is not officially supported

i was wondering if there is anything i can do to fix this or am i SOL and will need a new computer to play SL

please help thanks

I've got an nvidia 8400 and it is not at all happy with the new client. Try installing 1.19 again, I'd love to install the previous client version of 1.20 which was happy as Larry with my PC but I can't find a download for it.

i saw stuff in the forums about the previous versions and non offical LL clients working better on certain systems if it is possible for anyone to give me a link i would love to try this out

also if forgot to mention that this same laptop can run WoW 2.4.x and the leaked WotLK expansion, the Hellgate: London beta (with poor performance) and RollerCoaterTycoon3 plus the soaked expansion pack just fine and i have freind that play SL on older computers (one being a windows 95 model) and experience slight lag

UPDATE:

i found a download for the 1.19 release and i have now been able to log in and play see you all there
