The hard limit on the number of address book entries is "however many you can squeeze into the remainder of the 32 megs after OS, Calendar, email, memos, tasks"
Theoretically, each contact with minimal information in it will take up about 150Bytes (give or take). So, you can get about 6.5 contacts per KByte. 4.0 OS takes about 8Meg...so your 32Meg device is now at 24. Assuming you have absolutely nothing but contacts (with minimal information in them) you should be able to get about 159744 contacts on your BlackBerry. So I guess that would be the theoretical maximum.
Now, how many people actually use the BB for JUST contacts? So, every email is going to take up some space, and every calendar item (these can actaully be quite large....like 1.5k each), and every task, and every photo, and every attachment, etc...
