Use a lookup table - you can compensate for the thermistor
nonlinearity, and the nonlinearity of using a simple resistive divider
in one go. You can generate the table using the equation from the
thermistor databook data with a simple Basic/[insert your favorite
language] program, or probably Excel.

If you need a wide temperature range, use 2 switchable pullups to
improve linearity at the hot end, otherwise select the pullup/pulldown
to get a reasonable voltage swing over the range you're interested in.
