Removing Cydia is a pretty bad idea. It is unlikely it was broken, and getting rid of it is a bad choice!
Your best bet, since the singing window for 5.0.1 is still open, is to backup your iPad, restore to a stock / clean 5.0.1 firmware using iTunes, then immediately re-jailbreak using Absinthe, then restore you backup (if required).
I accidentally did the same thing. I scoured the net for tutorial on how to install cydia manually. Couldn't come up with one. Ended up restoring 5.01 and re-jailbreaking.
