in 10.7.1 I've also got KP with sleepenabler, but after I removed it, removed nullPM, use nativ ApplePM with speedstep everything works fine, temp is bit higher, but not as in snowleopard. and voodooHDA KP on startup disappeared and no more freeze during flash video in browser

Try this sleepenabler for LION 10.7.1. No panic here using this one

I must say that custom DSDT file fixed my D630 shutdown issues w/A17 BIOS!!. Now everything seems to be working just fine here. I also installed EDP package and that too worked out great. Thanks a lot. This forum is a great resource for users with Dell latitudes.
