Thanks for posting this! Very nice and clear photos.
If you don't want to grind the FET body, you can also mount it right-side-up. This is my preferred method because I am lazy and I don't want the LED- to be able to touch the top of the pill in those lights where I can push it all the way in.
STAR FW works as well if you want turbo timer, etc. Just change TCCR0A = 0x23 to TCCR0A = 0x21. This works in both normal and momentary versions. It doesn't have any strobe or ramping features though like luxdrv.
Here's a really bad cellphone picture that I took of my first one, which is obviously not very polished:

You can move it further inbound and still flash the driver if needed. I cut the legs shorter then bend them down until they are close to the required output pad then solder in place. This first one isn't quite where I place them now, but you can get the idea.
