Timbaland and Lex Lugar are diff entities with waaaaayyyyyyy different drums.
Get the hype out of your head that Quantizing is bad. in Hip Hop programming and quantizing is essential EXCEPT in the rare occasion you want a live sound(Roots, Dilla, ect)in which case, I'd just bust out my kid's drum set and mic it up for the genuine sound.
I'll give away the biggest secret I know(since I can't use it without sounding like dude). Timbaland beatboxes drum patterns(percs and all)think like Doug E Fresh. He just finds the sounds that fits whats going on in his head, and when the track is laid in the end, the drums sound crazy and unorthodox because you never beatbox "boom kak, boboom boom kak", it's more like "BzzzPahTickClik, BaBzzTickTickShhhClick"
Also the reason he often beatboxes into the tracks. Sometimes it's to give him a starting template, sometimes it's because he can't catch the vibe he wanted and once he beatboxes into the track it sounds right.
