Hi,
looks like multirow doesn't work too well with array environments. But I got it to work by replacing the multirow part of your array with this:

\multirow{2}{*}[1.4ex]
{
\text{$\displaystyle \left( \begin{array}{c} b_1 \\ b_2 \\ [0.3ex] b_3 \\ b_4 \\ \end{array} \right)$}
All I did was switch to text mode in the array, and this was enough to fool multicol into behaving properly. Within that, I switched back to math for the vector column.

Cheers,
Jens
