OS X Leopard on Toshiba laptop

jas osx86 10.5.4 running on a Toshiba Satellite L305-S5919 Intel Celeron 2.16 GHz, 2 GB RAM, 9.77 gigabytes HFS + partition from what I tested: Things that do not work:-built-in keyboard / trackpad (need use USB keyboard / mouse), graphic-sound-board-only displays in 1024x768, should go to 1280x800-saver and some applications (such as Photo Booth) will not run-Built-in multi-card reader-USB multi-card reader - network adapters (wired / wireless), DVD-movies (I suspect the data disks) ThingsThat work:-Finder menu (including the cover-flow)-most applications (not tested all)-Dashboard, Encore, Spaces -Log-in/out is probably more, but that's all I tested. Could not find any drivers (kext in OS XI do you think?) So unbearably high incompatibility.
