a. Dell Latitude D420, Core Solo 1064MHz b. No c. No d. My version, dunno if it is included as an option e. No, native speestep. f. No (Core Solo) g. Yes (+VoodooHDA) h. Yes, RC5m-1291. Now I prefer Clover, although it is not finished - no resume from sleep at the moment. i. Yes. It was needed for old version of Clover. Now I can return to vanilla kernel but see no sense. My kernel is better proved by month testing by tens of testers.

No need to switch on/off bluetooth if you choose right PS2 package. I see no any "mutli touch" options. What do you want to touch multi times?

ApplePS2Trackpad: ALPS GlidePoint v10.115 Same version that I have on Dell inspiron 1525. So my kext was tested for this model.

kernel.log If anyone wants a support then read here https://osxlatitude.com/index.php?/topic/207-how-to-test-drivers-and-report-a-result/

For some reason 4311 is not a best choice for MacOSX. You may emulate 4312 Method (_DSM, 4, NotSerialized) { Store (Package () { "device-id", Buffer () { 0x12, 0x43, 0x00, 0x00 }, "name", Buffer () { "pci14e4,4312" }, "model", Buffer (0x13) { "Dell Wireless 1395" }, "device_type", Buffer (0x08) { "Airport" }, "built-in", Buffer (One) { 0x00 } }, Local0) DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0)) Return (Local0) }

There is another hardware or just quirky hands.

Why? My kext is better then debug version and works with vanilla Trackpad.prefPane.

I always see those lags if dropbox updated or some other HDD activity. But it is not related to keyboard driver. And I see no diff between 10.6.6 and 10.6.7.

I forget to propose my last version from 03.03.2011, I also forgot to test it. Now I see it works. RC5m-749.zip

At the topic...

TrackPad and Keyboard are in the same PS2Controller. So influence is possible. -Dragging works if press touchpad more tightly. Finger size sensitive! -sticky is a normal. I like it.

There are two different drivers. 1. VoodooPS2Controller. No NUB needed. 2. ApplePS2Controller. NUB needed. Both you can download from the first post, NUB included. I prefer second solution. It seems work better after wake from sleep. In both cases you can put PS2Keyboard and PS2Trackpad kexts into plugin folder inside Controller kexts. Both VoodooPS2Keyboard and ApplePS2Keyboard works with both controllers. Again, I prefer ApplePS2 solution.

Dunno where can I place the information Edit by admin: "Infact I do! We are gonna use this page to collect all the benchmarks scores from our members, so I can add them to the benchmark wiki!

I corrected voltage for Yonah and Merom CPU. Updated version in topic. If you not agree with a temperature you can change TjMax value. Automatic calculated value you can see in your kernel log. For me 85. If you propose that temperature must be higher, set your own value in IntelCPUMonitor.info.plist using PlistEditor.
