i'll try to remember:123454321...(in all major/minor/dim7th keys)121234343545432321...(you can do these hands apart and then together)1324354231...31, 42, 53, 42, 31... things like this. over and over and different variations (say two times 31, 42, 31, 42...then 53, 42, 53, 42)it helps you quickly go through all the keys with the right sharps and flats, too (just for the five fingers). scales are another good exercise - because they do strengthen your fingers after awhile. my teacher used to have us 'block' scale patterns to the thumb (play all the notes together)CDE FGAB CDE FGAB - you play them really solidly up and down the keyboard. having the other fingers to support your weak ones - means you learn how to 'compensate' and still get a good sound from the 'whole.' no notes should be weaker sounding than others.
Just a few additional questions (kriskicksass): Did you find some of the first Dohnany excersies particularly helpful? Can you remember? I had a look at them, they seem well-conceived, I am just a bit worried that they might produce tension in hand, wrist and forearm, which would backfire on evenness.
