Windows 7: Toshiba portege m800 graphics driver issue

hi,
I have a toshiba portege m800, and i have found that running games that required 3d graphics acceleration do not run on windows 7 supplied drivers, i have an intel integrated graphics accelerator on board, windows vista drivers seem to ammend this problem but I constantly get drop outs, saying the display driver had an unexpected error and recovered successfully, anyone else having similar problems? when will toshiba be releasing official windows 7 drivers for this model? thanks Ant =-)
