Cutting the taproot is apparently not a problem. There's lots of good
info here:
http://aggie-horticulture.tamu.edu/extension/homefruit/pecan/pecan.html
"Dig the planting hole only as large as the root system (Figure 2). Extra
deep or large holes back-filled with soil allow the tree to settle. Settling
or planting too deep can cause root damage that results in poor growth or
death of the tree. To avoid settling, rest the base of the taproot firmly
against the bottom of the hole. If the hole is at least 2 feet deep and the
taproot is longer, cut the taproot off to fit the hole."
