You could get a midi out drum pad (one of those square ones, say from roland or alike) and a pair of sticks.
Then enter each drum part at a time (say hi hat first, then kick etc). That will give you a realistic feel.
Opposed to that search on the net for some midi drum loops that are played in by a real drummer, not put in by mouse.
I have a few but they are mapped for the Drumkit From Hell layout. If you want I can send you the midi files + a jpg of the DFH layout on a keyboard.
(These beats are played in by Thomas Haake of Meshuggah
