make sure you have not touched/modded original kexts in sys/lib/ext any intel graphics kext if so i suggest
fresh install of lion and this solution
here is a solution for anyone having trouble take the AppleIntelGMAX3100FB.kext from any snow leo install s/l/e and overwrite/install it on lion s/l/e use
kext wizard. attached is mine from snowleo it worked for me so try it
the original lion AppleIntelGMAX3100FB.kext. save it if you like but not necessary
repair perm after with kext wizard reboot with boot flags: arch=i386 -v (so your 32bit)
then should work perf accelerated graphics,dvd,perfect
