Working off of One Crayon's solution, I have something that works for me and is simpler:

.font2 {font-family:Arial; font-size:32px} /* Sample font */

  vertical-align: middle;
  position: relative;
  bottom: 1px;
}

input[type=radio] { 
  bottom: 2px; 
}

Renders pixel-for-pixel the same in Safari (whose baseline I trust) and both Firefox and IE7 check out as good. It also works for various label font sizes, big and small. Now, for fixing IE's baseline on selects and inputs...

Update: (Third-Party Edit)

The proper bottom position depends on font-family and font-size! I found using bottom: .08em; for checkbox & radio elements is a good general value. I tested it in Chrome/Firefox/IE11 in windows with Arial & Calibri fonts using several small/mid/large font-sizes.

.font2, .font2 input {font-family:Arial; font-size:32px} /* Sample font */

input[type=checkbox], input[type=radio] {
  vertical-align: middle; 
  position: relative;
  bottom: .08em; /* this is a better value for different fonts! */
}
