locked out of venue pro, need to perform hardware master reset!

so i changed the password on my DVP and now i stupidly cannot remember.  i've inputted too many incorrect password pin's in that now i'm locked out of the phone for 8 minutes with every incorrect pin input.

how do i perform a hardware master reset to wipe everything clean? i can't do the software master reset because i have no access to the main settings pain (locked out).  is there a way i can wipe it clean through zune? i'm not too worried about data loss because after i reset it i can simply sync it back with my laptop where i have my data backed up. 

thanks!
